In the United States, fiscal and functional federalism strongly shape public health policy and programs. Federalism has implications for public health practice: it molds financing and disbursement options, including funding formulas, which affect allocations and program goals, and shapes how funding decisions are operationalized in a political context. This article explores how American federalism, both fiscal and functional, structures public health funding, policy, and program options, investigating the effects of intergovernmental transfers on public health finance and programs.

Strongly interacting Fermi gases

Directory of Open Access Journals (Sweden)

Bakr W.

2013-08-01

Full Text Available Strongly interacting gases of ultracold fermions have become an amazingly rich test-bed for many-body theories of fermionic matter. Here we present our recent experiments on these systems. Firstly, we discuss high-precision measurements on the thermodynamics of a strongly interacting Fermi gas across the superfluid transition. The onset of superfluidity is directly observed in the compressibility, the chemical potential, the entropy, and the heat capacity. Our measurements provide benchmarks for current many-body theories on strongly interacting fermions. Secondly, we have studied the evolution of fermion pairing from three to two dimensions in these gases, relating to the physics of layered superconductors. In the presence of p-wave interactions, Fermi gases are predicted to display toplogical superfluidity carrying Majorana edge states. Two possible avenues in this direction are discussed, our creation and direct observation of spin-orbit coupling in Fermi gases and the creation of fermionic molecules of 23Na 40K that will feature strong dipolar interactions in their absolute ground state.

[Public health, prevention and federalism: insights from the implementation of the federal law on health insurance].

Science.gov (United States)

Rüefli, Christian; Sager, Fritz

2004-01-01

In 1996, the new Swiss law on health care insurance (KVG) introduced the coverage of certain preventive measures. This provided an opportunity to include research-based public health issues in federal health policy. The present article examines the problems with which the realization of those goals in a Federalist health care system with strong cantonal autonomy as it is found in Switzerland was confronted. Comparative qualitative case studies design (vaccination of school age children and screening-mammography). Switzerland's federalist health care system strongly hinders the realisation of the Confederation's public health goals. Prevention falls into the cantons' autonomy and the federal KVG (Krankenversicherungsgesetz; Health insurance law) only regulates the coverage of the services provided, but does not contain any instruments to assure implementation in consistency with the policy goals. Under those circumstances, conflicts of interest between the implementing actors, varying cantonal preferences, and scarce resources block the implementation of public health goals. The results imply stronger leadership of the Confederation in prevention policy and an improved consideration of implementation aspects in approving new measures to obligatory insurance coverage.

EPA perspective on federal facility agreements

International Nuclear Information System (INIS)

Grundler, C.

1988-01-01

Although DOE's image with Congress and the media concerning environmental compliance may be poor, EPA sees the Department's recent attitude toward the environment as good. DOE and EPA must continue to move forward. In particular, EPA would like to emphasize less study of a problem and more clean-up. Strong, enforceable agreements will allow this goal to be met by letting EPA take more risks in its decision making. Currently EPA is developing an enforcement strategy for Federal facilities. This strategy will address identifying Federal facilities of concern, increasing enforcement and compliance monitoring activities at those facilities, implementing the model agreements, resource planning, and the establishment of an Agency Management System for Federal facilities. There are over 1000 Federal facilities which are listed on the EPA compliance docket. Over 200 Federal facilities are expected to be included on the NPL. Increased EPA attention may increase the ability of the various Federal agencies to obtain the necessary funding. Another subject being addressed by EPA is the liability of government contractors under the environmental statutes. The Agency is developing a GoCo enforcement strategy. In the hazardous waste enforcement program, three criteria are being considered for determining when to proceed against a contractor: Degree of contractor control over the hazardous waste management activity. Who is actually performing the work, and Degree of Departmental cooperation

2012-01-01

We investigate the Jeans instability of self-gravitating magnetized strongly coupled plasma. The equations of the problem are formulated using the generalized hydrodynamic model and a general dispersion relation is obtained using the normal mode analysis. This dispersion relation is discussed for transverse and longitudinal mode of propagations. The modified condition of Jeans instability is obtained for magnetized strongly coupled plasma. We find that strong coupling of plasma particles modify the fundamental criterion of Jeans gravitational instability. In transverse mode it is found that Jeans instability criterion gets modified due to the presence of magnetic field, shear viscosity and fluid viscosity but in longitudinal mode it is unaffected due to the presence of magnetic field. From the curves we found that all these parameters have stabilizing influence on the growth rate of Jeans instability.

ANALYSIS OF CHP POTENTIAL AT FEDERAL SITES

Energy Technology Data Exchange (ETDEWEB)

HADLEY, S.W.

2002-03-11

This document was prepared at the request of the U.S. Department of Energy's (DOE's) Federal Energy Management Program (FEMP) under its Technical Guidance and Assistance and Project Financing Programs. The purpose was to provide an estimate of the national potential for combined heat and power (also known as CHP; cogeneration; or cooling, heating, and power) applications at federal facilities and the associated costs and benefits including energy and emission savings. The report provides a broad overview for the U.S. Department of Energy (DOE) and other agencies on when and where CHP systems are most likely to serve the government's best interest. FEMP's mission is to reduce the cost to and environmental impact of the federal government by advancing energy efficiency and water conservation, promoting the use of renewable energy, and improving utility management decisions at federal sites. FEMP programs are driven by its customers: federal agency sites. FEMP monitors energy efficiency and renewable energy technology developments and mounts ''technology-specific'' programs to make technologies that are in strong demand by agencies more accessible. FEMP's role is often one of helping the federal government ''lead by example'' through the use of advanced energy efficiency/renewable energy (EERE) technologies in its own buildings and facilities. CHP was highlighted in the Bush Administration's National Energy Policy Report as a commercially available technology offering extraordinary benefits in terms of energy efficiencies and emission reductions. FEMP's criteria for emphasizing a technology are that it must be commercially available; be proven but underutilized; have a strong constituency and momentum; offer large energy savings and other benefits of interest to federal sites and FEMP mission; be in demand; and carry sufficient federal market potential. As discussed in the report, CHP meets all

The Earth System Grid Federation (ESGF) experienced a major setback in June 2015, when it experienced a security incident that brought all systems to a halt for more than half a year. However, federation developers and management committee members turned the incident into an opportunity to dramatically upgrade the system security and functionality and to develop planning and policy documents to guide ESGF evolution and success. Moreover, despite the incident, ESGF developer working teams continue to make strong and significant progress on various enhancement projects that will help ensure ESGF can meet the needs of the climate community in the coming years.

Chaos-assisted tunneling in the presence of Anderson localization.

Doggen, Elmer V H; Georgeot, Bertrand; Lemarié, Gabriel

2017-10-01

Tunneling between two classically disconnected regular regions can be strongly affected by the presence of a chaotic sea in between. This phenomenon, known as chaos-assisted tunneling, gives rise to large fluctuations of the tunneling rate. Here we study chaos-assisted tunneling in the presence of Anderson localization effects in the chaotic sea. Our results show that the standard tunneling rate distribution is strongly modified by localization, going from the Cauchy distribution in the ergodic regime to a log-normal distribution in the strongly localized case, for both a deterministic and a disordered model. We develop a single-parameter scaling description which accurately describes the numerical data. Several possible experimental implementations using cold atoms, photonic lattices, or microwave billiards are discussed.

We have calculated the structural properties of a strange quark star with a static model in the presence of a strong magnetic field.To this end,we use the MITbag model with a density dependent bag constant.To parameterize the density dependence of the bag constant,we have used our results for the lowest order constrained variational calculation of the asymmetric nuclear matter.By calculating the equation of state of strange quark matter,we have shown that the pressure of this system increases by increasing both density and magnetic field.Finally,we have investigated the effect of density dependence of the bag constant on the structural properties of a strange quark star.

Processes of Individualization in the Presence of Strong Collective Identities

Directory of Open Access Journals (Sweden)

Atanasov, Petar

2016-04-01

Full Text Available In the contemporary societies people try to build an individualized approach through life, while the collective identity coercions starts to pale. This ratio consists of many aspects like the intensity of the existing collective identities, the consistency of transmission of the parent’s way of living to their children and the individual choices that are available for the young people in the specific social context. In Macedonian society there are some modern processes concerning the development of stronger personal identities of the youth, and their attempts to change the way of living comparing the way their parents did. Having in mind that in Macedonia live citizens that are members of different cultural and ethnic groups the analysis will show even local differences elaborating these phenomena. There are indications that there is some fluctuation towards bigger individualization among youth and the evidence that the young people still lives their parent’s collective identities. The target group of the research is the student population, in the study that was done on the sample of 707 respondents, chosen by quotas, from the six universities in the country. The main thesis is that the students are still “overshadowed of the successes” of their parents past social experience, that is strongly connected with the collective nature of their identities. The main research questions are the state of the collective identities, the relation between the parents and the student’s collective identification, and the evidence of stronger development of the self-confidence among students.

Federal role and activities in energy research and development 1946-1980: an historical summary

The federal role in energy research and development has changed substantially in the three decades since World War II. In nuclear technology, the federal presence shifted from government monopoly in the 1940s and early 1950s, to a lesser federal role in the mid-1950s, as the private sector commercialized nuclear power, to an increasing federal role in the 1960s, but now focused on the breeder reactor as a long-term option. Conventional fuel technologies such as coal and oil enjoyed only modest federal support in the immediate postwar years, with only slow increases before 1974. Renewable energy technologies have received substantial federal support only since 1973.

Detailed site effect estimation in the presence of strong velocity reversals within a small-aperture strong-motion array in Iceland

KAUST Repository

Rahpeyma, Sahar

2016-08-11

The rock site characterization for earthquake engineering applications in Iceland is common due to the easily exposed older bedrock and more recent volcanic lava rock. The corresponding site amplification is generally assumed to be low but has not been comprehensively quantified, especially for volcanic rock. The earthquake strong-motion of the Mw6.3 Ölfus earthquake on 29 May 2008 and 1705 of its aftershocks recorded on the first small-aperture strong-motion array (ICEARRAY I) in Iceland showed consistent and significant variations in ground motion amplitudes over short distances (<2 km) in an urban area located mostly on lava rock. This study analyses the aftershock recordings to quantify the local site effects using the Horizontal to Vertical Spectral Ratio (HVSR) and Standard Spectral Ratio (SSR) methods. Additionally, microseismic data has been collected at array stations and analyzed using the HVSR method. The results between the methods are consistent and show that while the amplification levels remain relatively low, the predominant frequency varies systematically between stations and is found to correlate with the geological units. In particular, for stations on lava rock the underlying geologic structure is characterized by repeated lava-soil stratigraphy characterized by reversals in the shear wave velocity with depth. As a result, standard modeling of HVSR using vertically incident body waves does not apply. Instead, modeling the soil structure as a two-degree-of-freedom dynamic system is found to capture the observed predominant frequencies of site amplification. The results have important implications for earthquake resistant design of structures on rock sites characterized by velocity reversals. © 2016 Elsevier Ltd

Strong advocacy led to successful implementation of smokefree Mexico City.

Crosbie, Eric; Sebrié, Ernesto M; Glantz, Stanton A

2011-01-01

To describe the approval process and implementation of the 100% smokefree law in Mexico City and a competing federal law between 2007 and 2010. Reviewed smokefree legislation, published newspaper articles and interviewed key informants. Strong efforts by tobacco control advocacy groups and key policymakers in Mexico City in 2008 prompted the approval of a 100% smokefree law following the WHO FCTC. As elsewhere, the tobacco industry utilised the hospitality sector to block smokefree legislation, challenged the City law before the Supreme Court and promoted the passage of a federal law that required designated smoking areas. These tactics disrupted implementation of the City law by causing confusion over which law applied in Mexico City. Despite interference, the City law increased public support for 100% smokefree policies and decreased the social acceptability of smoking. In September 2009, the Supreme Court ruled in favour of the City law, giving it the authority to go beyond the federal law to protect the fundamental right of health for all citizens. Early education and enforcement efforts by tobacco control advocates promoted the City law in 2008 but advocates should still anticipate continuing opposition from the tobacco industry, which will require continued pressure on the government. Advocates should utilise the Supreme Court's ruling to promote 100% smokefree policies outside Mexico City. Strong advocacy for the City law could be used as a model of success throughout Mexico and other Latin American countries.

Flavour Democracy in Strong Unification

1998-01-01

We show that the fermion mass spectrum may naturally be understood in terms of flavour democratic fixed points in supersymmetric theories which have a large domain of attraction in the presence of "strong unification". Our approach provides an alternative to the approximate Yukawa texture zeroes of the Froggatt-Nielsen mechanism. We discuss a particular model based on a broken gauged $SU(3)_L\\times SU(3)_R$ family symmetry which illustrates our approach.

Strongly interacting matter in magnetic fields

Landsteiner, Karl; Schmitt, Andreas; Yee, Ho-Ung

2013-01-01

The physics of strongly interacting matter in an external magnetic field is presently emerging as a topic of great cross-disciplinary interest for particle, nuclear, astro- and condensed matter physicists. It is known that strong magnetic fields are created in heavy ion collisions, an insight that has made it possible to study a variety of surprising and intriguing phenomena that emerge from the interplay of quantum anomalies, the topology of non-Abelian gauge fields, and the magnetic field. In particular, the non-trivial topological configurations of the gluon field induce a non-dissipative electric current in the presence of a magnetic field. These phenomena have led to an extended formulation of relativistic hydrodynamics, called chiral magnetohydrodynamics. Hitherto unexpected applications in condensed matter physics include graphene and topological insulators. Other fields of application include astrophysics, where strong magnetic fields exist in magnetars and pulsars. Last but not least, an important ne...

The proposed use of irradiation in food processing is drawing considerable attention to the Australian irradiation industry that has operated safely for almost 30 years. A recent inquiry by the Australian Consumers Association concluded that food irradiation should only be allowed if strong federal laws are implemented to ensure the safety of consumers and environment. At present, Australian irradiation plants are confined to sterilising or reducing health risks associated with products not for human consumption

New particle formation in the presence of a strong biomass burning episode at a downwind rural site in PRD, China

Full Text Available In order to characterise the features of particle pollution in the Pearl River Delta (PRD region, a 1-month intensive campaign was conducted at the rural supersite (Kaiping in the autumn of 2008. In total, 12 new particle formation (NPF events are identified out of 30 campaign days. The results show that in the case of higher source and sink values, the result of the competition between source and sink is more likely the key limiting factor to determine the observation of NPF events at Kaiping. One episode with consecutive NPF events in the presence of strong biomass burning plume was observed between 10 and 15 November. The elevation of particle volume concentration (6.1 µm3/cm3/day is due to the coaction by the local biomass burning and secondary transformation. Organics and sulphates are the major components in PM1, accounting for 42 and 35% of the mass concentration, respectively. In this study, a rough estimation is applied to quantify the contributions of diverse sources to the particle number concentration. On average, the primary emission and secondary formation provide 28 and 72% of particle number concentration and 21 and 79% of mass concentration, respectively.

Gamma ray spectra of strong (241)Am sources may reveal information about the source composition as there may be other radioactive nuclides such as progeny and radioactive impurities present. In this work the possibility to use gamma spectrometry to identify inherent signatures in (241)Am sources in order to differentiate sources from each other, is investigated. The studied signatures are age, i.e. time passed since last chemical separation, and presence of impurities. The spectra of some sources show a number of Doppler broadened peaks in the spectrum which indicate the presence of nuclear reactions on light elements within the sources. The results show that the investigated sources can be differentiated between by age and/or presence of impurities. These spectral features would be useful information in a national nuclear forensics library (NNFL) in cases when the visual information on the source, e.g. the source number, is unavailable.

Strong-Weak CP Hierarchy from Non-Renormalization Theorems

Energy Technology Data Exchange (ETDEWEB)

Hiller, Gudrun

2002-01-28

We point out that the hierarchy between the measured values of the CKM phase and the strong CP phase has a natural origin in supersymmetry with spontaneous CP violation and low energy supersymmetry breaking. The underlying reason is simple and elegant: in supersymmetry the strong CP phase is protected by an exact non-renormalization theorem while the CKM phase is not. We present explicit examples of models which exploit this fact and discuss corrections to the non-renormalization theorem in the presence of supersymmetry breaking. This framework for solving the strong CP problem has generic predictions for the superpartner spectrum, for CP and flavor violation, and predicts a preferred range of values for electric dipole moments.

As the game industry expresses a growing demand for effective evaluation methods, it is worth investigating if the commonly used questionnaires can be replaced by alternative ways of measuring user experience in interactive environments. This paper describes an experiment where an existing presence...... measurement method is modified for use in computer game development. 39 subjects were part of the experiment, which was designed to test applicability of the adapted presence measuring method. Besides playing a game prototype, test participants were asked to press a button when a visual signal, triggered...... by an in-game event, would appear on the screen in the periphery of sight. Noting how strong the signal was is assumed to infer how strong the stimuli had to be in order to break the immersive presence. The results indicated that the adapted method with observations from the test is more useful, than...

One-loop QCD thermodynamics in a strong homogeneous and static magnetic field

Science.gov (United States)

Rath, Shubhalaxmi; Patra, Binoy Krishna

2017-12-01

We have studied how the equation of state of thermal QCD with two light flavors is modified in a strong magnetic field. We calculate the thermodynamic observables of hot QCD matter up to one-loop, where the magnetic field affects mainly the quark contribution and the gluon part is largely unaffected except for the softening of the screening mass. We have first calculated the pressure of a thermal QCD medium in a strong magnetic field, where the pressure at fixed temperature increases with the magnetic field faster than the increase with the temperature at constant magnetic field. This can be understood from the dominant scale of thermal medium in the strong magnetic field, being the magnetic field, in the same way that the temperature dominates in a thermal medium in the absence of magnetic field. Thus although the presence of a strong magnetic field makes the pressure of hot QCD medium larger, the dependence of pressure on the temperature becomes less steep. Consistent with the above observations, the entropy density is found to decrease with the temperature in the presence of a strong magnetic field which is again consistent with the fact that the strong magnetic field restricts the dynamics of quarks to two dimensions, hence the phase space becomes squeezed resulting in the reduction of number of microstates. Moreover the energy density is seen to decrease and the speed of sound of thermal QCD medium increases in the presence of a strong magnetic field. These findings could have phenomenological implications in heavy ion collisions because the expansion dynamics of the medium produced in non-central ultra-relativistic heavy ion collisions is effectively controlled by both the energy density and the speed of sound.

Strongly interacting light dark matter

International Nuclear Information System (INIS)

Bruggisser, Sebastian; Riva, Francesco; Urbano, Alfredo

2016-07-01

In the presence of approximate global symmetries that forbid relevant interactions, strongly coupled light Dark Matter (DM) can appear weakly coupled at small-energy and generate a sizable relic abundance. Fundamental principles like unitarity restrict these symmetries to a small class, where the leading interactions are captured by effective operators up to dimension-8. Chiral symmetry, spontaneously broken global symmetries and non-linearly realized supersymmetry are examples of this. Their DM candidates (composite fermions, pseudo-Nambu-Goldstone Bosons and Goldstini) are interesting targets for LHC missing-energy searches.

Insurer Competition In Federally Run Marketplaces Is Associated With Lower Premiums.

Science.gov (United States)

Jacobs, Paul D; Banthin, Jessica S; Trachtman, Samuel

2015-12-01

Federal subsidies for health insurance premiums sold through the Marketplaces are tied to the cost of the benchmark plan, the second-lowest-cost silver plan. According to economic theory, the presence of more competitors should lead to lower premiums, implying smaller federal outlays for premium subsidies. The long-term impact of the Affordable Care Act on government spending will depend on the cost of these premium subsidies over time, with insurer participation and the level of competition likely to influence those costs. We studied insurer participation and premiums during the first two years of the Marketplaces. We found that the addition of a single insurer in a county was associated with a 1.2 percent lower premium for the average silver plan and a 3.5 percent lower premium for the benchmark plan in the federally run Marketplaces. We found that the effect of insurer entry was muted after two or three additional entrants. These findings suggest that increased insurer participation in the federally run Marketplaces reduces federal payments for premium subsidies.

In vitro transcription in the presence of DNA oligonucleotides can generate strong anomalous initiation sites.

Science.gov (United States)

Chow, C W; Clark, M P; Rinaldo, J E; Chalkley, R

1996-03-01

In the present study, we have explored an unexpected observation in transcription initiation that is mediated by single-stranded oligonucleotides. Initially, our goal was to understand the function of different upstream regulatory elements/initiation sites in the rat xanthine dehydrogenase/oxidase (XDH/XO) promoter. We performed in vitro transcription with HeLa nuclear extracts in the presence of different double-stranded oligonucleotides against upstream elements as competitors. A new and unusual transcription initiation site was detected by primer extension. This new initiation site maps to the downstream region of the corresponding competitor. Subsequent analyses have indicated that the induction of a new transcription initiation site is anomalous which is due to the presence of a small amount of single-stranded oligonucleotide in the competitor. We found that this anomalous initiation site is insensitive to the orientation of the promoter and requires only a small amount of single-stranded oligonucleotide (< 2-fold molar excess relative to template). We surmise that a complementary interaction between the single-stranded oligonucleotide and transiently denatured promoter template may be responsible for this sequence-specific transcription initiation artifact. To study the regulation of transcription initiation by in vitro transcription approaches, we propose that one should probe the effect of removing transacting factors by adding an excess of a cognate oligonucleotide which does not bear exact sequence identity to the template.

Assessment of potential positive effects of nZVI surface modification and concentration levels on TCE dechlorination in the presence of competing strong oxidants, using an experimental design.

Nanoscale zero-valent iron (nZVI) particles are efficient for the remediation of aquifers polluted by trichloroethylene (TCE). But for on-site applications, their reactivity can be affected by the presence of common inorganic co-pollutants, which are equally reduced by nZVI particles. The aim of this study was to assess the potential positive effects of nZVI surface modification and concentration level on TCE removal in the concomitant presence of two strong oxidants, i.e., Cr(VI) and NO3(-). A design of experiments, testing four factors (i.e. nZVI concentration, nZVI surface modification, Cr(VI) concentration and NO3(-) concentration), was used to select the best trials for the identification of the main effects of the factors and of the factors interactions. The effects of these factors were studied by measuring the following responses: TCE removal rates at different times, degradation kinetic rates, and the transformation products formed. As expected, TCE degradation was delayed or inhibited in most of the experiments, due to the presence of inorganics. The negative effects of co-pollutants can be palliated by combining surface modification with a slight increase in nZVI concentration. Encouragingly, complete TCE removal was achieved for some given experimental conditions. Noteworthily, nZVI surface modification was found to promote the efficient degradation of TCE. When degradation occurred, TCE was mainly transformed into innocuous non-chlorinated transformation products, while hazardous chlorinated transformation products accounted for a small percentage of the mass-balance.

2009-01-01

To determine the influence of tobacco exposure in the development of metabolic syndrome (MS) in the adult Saudi population. Six hundred and sixty-four adults (305 males and 359 females) aged 25-70 years were included in this cross-sectional study conducted at the King Abdul Aziz University Hospital, between June 2006 and May 2007. We classified the participants into non-smokers, smokers, and ex-smokers (defined as complete cessation for 1-2 years). All subjects were screened for the presence of MS using the modified American Heart Association/National Heart, Lung and Blood Institute (AHA/NHLBI), International Diabetes Federation (IDF) and World Health Organization (WHO) definitions. Metabolic syndrome was highest among ex-smokers regardless of definition used. Relative risk for ex-smokers (95% CI: 2.23, 1.06-4.73) was more than twice in harboring MS as compared to non-smokers (95% CI: 2.78, 1.57-4.92) (p=0.009). Acute post-cessation smoking is a strong predictor for MS among male and female Arabs. Smoking cessation programs should include a disciplined lifestyle and dietary intervention to counteract the MS-augmenting side-effect of smoking cessation. (author)

From Policy to Compliance: Federal Energy Efficient Product Procurement

Federal buyers are required to purchase energy-efficient products in an effort to minimize energy use in the federal sector, save the federal government money, and spur market development of efficient products. The Federal Energy Management Program (FEMP)’s Energy Efficient Product Procurement (EEPP) Program helps federal agencies comply with the requirement to purchase energy-efficient products by providing technical assistance and guidance and setting efficiency requirements for certain product categories. Past studies have estimated the savings potential of purchasing energy-efficient products at over $500 million per year in energy costs across federal agencies.1 Despite the strong policy support for EEPP and resources available, energy-efficient product purchasing operates within complex decision-making processes and operational structures; implementation challenges exist that may hinder agencies’ ability to comply with purchasing requirements. The shift to purchasing green products, including energy-efficient products, relies on “buy in” from a variety of potential actors throughout different purchasing pathways. Challenges may be especially high for EEPP relative to other sustainable acquisition programs given that efficient products frequently have a higher first cost than non-efficient ones, which may be perceived as a conflict with fiscal responsibility, or more simply problematic for agency personnel trying to stretch limited budgets. Federal buyers may also face challenges in determining whether a given product is subject to EEPP requirements. Previous analysis on agency compliance with EEPP, conducted by the Alliance to Save Energy (ASE), shows that federal agencies are getting better at purchasing energy-efficient products. ASE conducted two reviews of relevant solicitations for product and service contracts listed on Federal Business Opportunities (FBO), the centralized website where federal agencies are required to post procurements greater

NeuroLOG: sharing neuroimaging data using an ontology-based federated approach.

This paper describes the design of the NeuroLOG middleware data management layer, which provides a platform to share heterogeneous and distributed neuroimaging data using a federated approach. The semantics of shared information is captured through a multi-layer application ontology and a derived Federated Schema used to align the heterogeneous database schemata from different legacy repositories. The system also provides a facility to translate the relational data into a semantic representation that can be queried using a semantic search engine thus enabling the exploitation of knowledge embedded in the ontology. This work shows the relevance of the distributed approach for neurosciences data management. Although more complex than a centralized approach, it is also more realistic when considering the federation of large data sets, and open strong perspectives to implement multi-centric neurosciences studies.

Federally mandating motorcycle helmets in the United States.

2016-03-09

Motorcycle helmets reduce both motorcycle-related fatalities and head injuries. Motorcycle crashes are a major public health concern which place economic stress on the U.S. healthcare system. Although statewide universal motorcycle helmet laws effectively increase helmet use, most state helmet laws do not require every motorcycle rider to wear a helmet. Herein, we propose and outline the solution of implementing federal motorcycle helmet law, while addressing potential counterarguments. The decision to ride a motorcycle without a helmet has consequences that affect more than just the motorcyclist. In an effort to prevent unnecessary healthcare costs, injuries, and deaths, public health efforts to increase helmet use through education and legislation should be strongly considered. Helmet use on motorcycles fits squarely within the purview of the federal government public health and economic considerations.

Strongly interacting Higgs sector without technicolor

Simulation results are presented on Higgs mass calculations in the spontaneously broken phase of the Higgs sector in the minimal Standard Model with a higher derviative regulator. A heavy Higgs particle is found in the TeV mass range in the presence of a complex conjugate ghost pair at higher energies. The ghost pair evades easy experimental detection. As a finite and unitary theory in the continuum, this model serves as an explicit and simple example of a strong interacting Higgs sector without technicolor. (orig.)

Energy policy in the Federal Republic of Germany

International Nuclear Information System (INIS)

Anon.

1986-01-01

The tenor and consensus of energy policy in the Federal Republic of Germany have been affected and shaken by the discussion of damage to forests at the beginning of 1985, the rapidly slumping petroleum prices, the Chernobyl reactor accident, and the resulting emotionalized energy policy debates overshadowing the elections for the Land government, the Senate and the Bundestag. However, the responsible decision making organs still seem to feel a strong need for a consensus of that kind. ET-editors have therefore been trying to find out about the situation of 'energy policy in the Federal Republic of Germany' late in 1986. The Federal Government, the parliamentary factions, the parties, Land governments, labor unions and BDI, the coal, petroleum and natural gas industry as well as the manufacturers and managers of nuclear power plants were asked to express their opinion on the following questions: How will the energy supply of the Federal Republic of Germany be provided for in the future. What are the pros and cons of a nuclear phase-out. Should energy economy be reorganized. What is expected from and desired for the development of individual regions or energy sources, respectively. All but a few of above organs answered the questions. The statements therefore give a representative survey of the opinions and attitudes of the relevant decision-making organs and of different institutions. (orig./UA) [de

Coulomb Impurity Problem of Graphene in Strong Coupling Regime in Magnetic Fields.

Science.gov (United States)

Kim, S C; Yang, S-R Eric

2015-10-01

We investigate the Coulomb impurity problem of graphene in strong coupling limit in the presence of magnetic fields. When the strength of the Coulomb potential is sufficiently strong the electron of the lowest energy boundstate of the n = 0 Landau level may fall to the center of the potential. To prevent this spurious effect the Coulomb potential must be regularized. The scaling function for the inverse probability density of this state at the center of the impurity potential is computed in the strong coupling regime. The dependence of the computed scaling function on the regularization parameter changes significantly as the strong coupling regime is approached.

Electrons in a strong magnetic field

International Nuclear Information System (INIS)

Itzykson, C.

1985-05-01

We first describe the average one-particle spectrum in the presence of a strong magnetic field together with random impurities for a Gaussian distribution, and generalized using a supersymmetric method. We then study the effect of Coulomb interactions on an electron gas in a strong field, within the approximation of a projection on the lowest Landau level. At maximal density (or filling fraction ν equal to unity) the quantum mechanical problem is equivalent to a soluble classical model for a two-dimensional plasma. As ν decreases, more states come into play. Laughlin has guessed the structure of the ground state and its low lying excitations for certain rational values of the filling fraction. A complete proof is however missing, nor is it clear what happens as ν becomes so small that a ''crystalline'' structure becomes favoured. Our presentation shows a link with functions occurring in combinatorics and analytic number theory, which seems not to have been fully exploited

BETWEEN EUROPEANIZATION, UNITARISM AND AUTONOMY. REMARKS ON THE CURRENT SITUATION OF FEDERALISM IN AUSTRIA

Directory of Open Access Journals (Sweden)

Peter Bußjäger

2010-04-01

Full Text Available The following article describes current challenges of Austrian federalism. On ground of the Federal Constitution from 1920 Austria is a federation with nine autonomous Länder. Federalism is one of the basic principles of the constitution. Nevertheless the Länder are faced with centralizing drive due to Europeanization and unitarism. On the other hand the Länder have a strong regional identity. The Länder are emotionally deeply rooted in theAustrian population. The Länder also participate well in the decision making process on European level.Nevertheless the division of competencies both in legislation and administration between Federation and Länder is complicated and needs to be modernised. In the past various reform projects on federal level had failed while various reforms in the Land constitutions have led to more innovation on Land level. Despite these facts paradigms of reform debates on Austria´s federal system have changed: Until the early nineties of 20th century constitutionalreforms aimed to strengthen the role of the Länder. Since Austria´saccession to the EU reform projects the efficiency of the federal structures of Austria are doubted. Economical and financial crisis probably will increase the pressure for structural reforms.

Hydrogen atoms in a strong magnetic field

International Nuclear Information System (INIS)

Santos, R.R. dos.

1975-07-01

The energies and wave functions of the 14 lowest states of a Hydrogen atom in a strong magnetic field are calculated, using a variational scheme. The equivalence between the atomic problem and the problems related with excitons and impurities in semiconductors in the presence of a strong magnetic field are shown. The calculations of the energies and wave functions have been divided in two regions: the first, for the magnetic field ranging between zero and 10 9 G; in the second the magnetic field ranges between 10 9 and 10 11 G. The results have been compared with those obtained by previous authors. The computation time necessary for the calculations is small. Therefore this is a convenient scheme to obtain the energies and wave functions for the problem. Transition probabilities, wavelengths and oscillator strengths for some allowed transitions are also calculated. (Author) [pt

Quantum electrodynamics in strong external fields

Mueller, B.; Rafelski, J.; Kirsch, J.

1981-05-01

We review the theoretical description of quantum electrodynamics in the presence of strong and supercritical fields. In particular, the process of the spontaneous vacuum decay accompanied by the observable positron emission in heavy ion collisions is described. Emphasis is put on the proper formulation of many-body aspects in the framework of quantum field theory. The extension of the theory to the description of Bose fields and many-body effects is presented, and the Klein paradox is resolved. Some implications of the theoretical methods developed here are presented concerning non-abelian gauge theories and the quark confinement puzzle. (orig.)

Though not a part of mainstream physics, Salam's theory of strong gravity remains a viable effective model for the description of strong interactions in the gauge singlet sector of QCD, capable of producing particle confinement and asymptotic freedom, but not of reproducing interactions involving SU(3) color charge. It may therefore be used to explore the stability and confinement of gauge singlet hadrons, though not to describe scattering processes that require color interactions. It is a two-tensor theory of both strong interactions and gravity, in which the strong tensor field is governed by equations formally identical to the Einstein equations, apart from the coupling parameter, which is of order 1 GeV{sup -1}. We revisit the strong gravity theory and investigate the strong gravity field equations in the presence of a mixing term which induces an effective strong cosmological constant, Λ{sub f}. This introduces a strong de Sitter radius for strongly interacting fermions, producing a confining bubble, which allows us to identify Λ{sub f} with the 'bag constant' of the MIT bag model, B ≅ 2 x 10{sup 14} g cm{sup -3}. Assuming a static, spherically symmetric geometry, we derive the strong gravity TOV equation, which describes the equilibrium properties of compact hadronic objects. From this, we determine the generalized Buchdahl inequalities for a strong gravity 'particle', giving rise to upper and lower bounds on the mass/radius ratio of stable, compact, strongly interacting objects. We show, explicitly, that the existence of the lower mass bound is induced by the presence of Λ{sub f}, producing a mass gap, and that the upper bound corresponds to a deconfinement phase transition. The physical implications of our results for holographic duality in the context of the AdS/QCD and dS/QCD correspondences are also discussed. (orig.)

Presence

Directory of Open Access Journals (Sweden)

Pamela Renee Boeck

2014-03-01

Full Text Available Healthy therapeutic relationships enhance wholeness and healing; they are the key to effective health promotion. Therapeutic nursing presence demonstrates caring, empathy, and connection, qualities required to build rapport and trust between nurse and patient. This concept analysis’ purpose was to illuminate the various forms of the meanings of presence and the value placed on them. The science of nursing often precedes the art and spirituality of nursing. This is due to focusing primarily on the high acuity of the patients being seen in conjunction with shortage of personnel and resources. Patient dissatisfaction continues to be a growing concern. The nursing shortage crisis continues along with more nurses experiencing moral distress, compassion fatigue, and/or burnout. In nurses’ haste to complete their duties, are we facing the risk of overlooking one of the original gifts of the nursing profession? This would be the gift of genuine presence. This concept analysis aims to identify the attributes that are essential to the concept of presence, and to clarify its nursing usage, by following the strategy suggested by Walker and Avant. It is important to reflect on various ways of providing presence in the clinical setting. By exploring the spiritual, literary, psychological, and nursing literature, there is a diverse yet similar interconnectivity of what presence may represent. Observations and experiences of a range of sensatory and kinesthetic perceptions are revealed to ascertain the attributes discerning commonalities and themes of presence. Nursing presence is considered to be an essential state of holistic nursing as well as a core competency in contemporary nursing. Clarifying the significance of presence in nursing invites the prospect of additional evidence-based research that may place the intrinsic value of presence as a continuing theoretical foundation.

Validation of numerical solvers for liquid metal flow in a complex geometry in the presence of a strong magnetic field

Patel, Anita; Pulugundla, Gautam; Smolentsev, Sergey; Abdou, Mohamed; Bhattacharyay, Rajendraprasad

2018-04-01

Following the magnetohydrodynamic (MHD) code validation and verification proposal by Smolentsev et al. (Fusion Eng Des 100:65-72, 2015), we perform code to code and code to experiment comparisons between two computational solvers, FLUIDYN and HIMAG, which are presently considered as two of the prospective CFD tools for fusion blanket applications. In such applications, an electrically conducting breeder/coolant circulates in the blanket ducts in the presence of a strong plasma-confining magnetic field at high Hartmann numbers, it{Ha} (it{Ha}^2 is the ratio between electromagnetic and viscous forces) and high interaction parameters, it{N} (it{N} is the ratio of electromagnetic to inertial forces). The main objective of this paper is to provide the scientific and engineering community with common references to assist fusion researchers in the selection of adequate computational means to be used for blanket design and analysis. As an initial validation case, the two codes are applied to the classic problem of a laminar fully developed MHD flows in a rectangular duct. Both codes demonstrate a very good agreement with the analytical solution for it{Ha} up to 15, 000. To address the capabilities of the two codes to properly resolve complex geometry flows, we consider a case of three-dimensional developing MHD flow in a geometry comprising of a series of interconnected electrically conducting rectangular ducts. The computed electric potential distributions for two flows (Case A) it{Ha}=515, it{N}=3.2 and (Case B) it{Ha}=2059, it{N}=63.8 are in very good agreement with the experimental data, while the comparisons for the MHD pressure drop are still unsatisfactory. To better interpret the observed differences, the obtained numerical data are analyzed against earlier theoretical and experimental studies for flows that involve changes in the relative orientation between the flow and the magnetic field.

Galactic cluster winds in presence of a dark energy

We obtain a solution for the hydrodynamic outflow of the polytropic gas from the gravitating centre, in the presence of the uniform dark energy (DE). The antigravity of DE is enlightening the outflow and makes the outflow possible at smaller initial temperature, at the same density. The main property of the wind in the presence of DE is its unlimited acceleration after passing the critical point. In application of this solution to the winds from galaxy clusters, we suggest that collision of the strongly accelerated wind with another galaxy cluster, or with another galactic cluster wind, could lead to the formation of a highest energy cosmic rays.

Density matrix of strongly coupled quantum dot - microcavity system

International Nuclear Information System (INIS)

Nguyen Van Hop

2009-01-01

Any two-level quantum system can be used as a quantum bit (qubit) - the basic element of all devices and systems for quantum information and quantum computation. Recently it was proposed to study the strongly coupled system consisting of a two-level quantum dot and a monoenergetic photon gas in a microcavity-the strongly coupled quantum dot-microcavity (QD-MC) system for short, with the Jaynes-Cumming total Hamiltonian, for the application in the quantum information processing. Different approximations were applied in the theoretical study of this system. In this work, on the basis of the exact solution of the Schrodinger equation for this system without dissipation we derive the exact formulae for its density matrix. The realization of a qubit in this system is discussed. The solution of the system of rate equation for the strongly coupled QD-MC system in the presence of the interaction with the environment was also established in the first order approximation with respect to this interaction.

We investigated how technologically mediating two different components of emotion-communicative expression and physiological state-to group members affects physiological linkage and self-reported feelings in a small group during video viewing. In different conditions the availability of second screen text chat (communicative expression) and visualization of group level physiological heart rates and their dyadic linkage (physiology) was varied. Within this four person group two participants formed a physically co-located dyad and the other two were individually situated in two separate rooms. We found that text chat always increased heart rate synchrony but HR visualization only with non-co-located dyads. We also found that physiological linkage was strongly connected to self-reported social presence. The results encourage further exploration of the possibilities of sharing group member's physiological components of emotion by technological means to enhance mediated communication and strengthen social presence.

Nuclear supervision - Administration by the federal states on behalf of the Federal Government or direct federal administration for optimum achievement

Renneberg, W.

2005-01-01

One year ago, Federal Minister for the Environment Juergen Trittin expressed doubt about the long-term viability of the federal states' acting on behalf of the federal government in the field of atomic energy law administration. An alternative to this type of administration was mentioned, namely direct execution by the feral government, and a thorough examination was announced. This was to show which type of administration would achieve maximum safety for the residual operating lives of nuclear power plants. Kienbaum Management Consultants were commissioned to evaluate the current status and potential alternative structures. That study was performed within the framework of one of the key projects in reactor safety of the Federal Ministry for the Environment, Nature Conservation, and Nuclear Safety (BMU), namely the reform of nuclear administration. Further steps to be taken by the BMU by the end of this parliamentary term are presented. The federal state are to be approached in an attempt to conduct an unbiased discussion of the pros and cons of the alternatives to administration by the federal states on behalf of the federal government. Questions will be clarified which need to be examined in depth before direct administration by the federal government can be introduced. These include constitutional matters and matters of costing in financing the higher-level federal authority as well as specific questions about the organization of that authority. The purpose is to elaborate, by the end of this parliamentary term, a workable concept of introducing direct federal administration of nuclear safety. (orig.)

Quantum key distribution based on encoding in three-dimensional systems in the presence of several eavesdroppers is proposed. This extends the BB84 protocol in the presence of many eavesdroppers where two-level quantum systems (qubits) are replaced by three-level systems (qutrits). We discuss the scenarios involving two, three and four complementary bases. We derive the explicit form of Alice and Bob mutual information and the information gained by each eavesdropper. In particular, we show that, in the presence of only one eavesdropper, the protocol involving four bases is safer than the other ones. However, for two eavesdroppers, the security is strongly dependent on the attack probabilities. The effect of a large number of eavesdroppers is also investigated.

Presence of virulence plasmid pYVwas determined by gel electrophoresis by T. Kieser method. 447 strains of Y. enterocolitica biotype 1A and 2 - 4 were studied. Most of the strains belonged to serotypes O:3; O:9; O: 5; O: 6,30; O:6,31; O:7,8. Phagotyping was performed for part of the strains. Phagotypes Xz and Xo were determined in biotype 1A strains. 2 - 4 biotype strains circulating in Siberia and the Far East were characterized by phagotype VIII, X3 that are present in other countries, and phagotype Xz that is spread only in Russia. Phagotypes IXa, IXb, II that are characteristic for strains from Canada, South Africa, Japan were not detected in Russian Federation. All the strains of 2 - 4 biotypes had ail and ystA genes. Most of the recently isolated strains had pYV. The only pathogenicity factor detected in 81.3% of biotype 1A strains including 14 strains from patients was ystB gene. These infections were accompanied by an expressed clinical symptomatology of enteritis and enterocolitis. Isolation of 1A biotype strains from patients necessitates execution of diagnostic studies of intestinal yersiniosis in patients with diagnosis "acute intestinal infection of undetermined etiology".

On Multiple Reconnection X-lines and Tripolar Perturbations of Strong Guide Magnetic Fields

We report new multi-spacecraft Cluster observations of tripolar guide magnetic field perturbations at a solar wind reconnection exhaust in the presence of a guide field BM which is almost four times as strong as the reversing field BL. The novel tripolar field consists of two narrow regions of depressed BM, with an observed 7%-14% ΔBM magnitude relative to the external field, which are found adjacent to a wide region of enhanced BM within the exhaust. A stronger reversing field is associated with each BM depression. A kinetic reconnection simulation for realistic solar wind conditions and the observed strong guide field reveals that tripolar magnetic fields preferentially form across current sheets in the presence of multiple X-lines as magnetic islands approach one another and merge into fewer and larger islands. The simulated ΔBM/ΔXN over the normal width ΔXN between a BM minimum and the edge of the external region agree with the normalized values observed by Cluster. We propose that a tripolar guide field perturbation may be used to identify candidate regions containing multiple X-lines and interacting magnetic islands at individual solar wind current sheets with a strong guide field.

We study the stability and energetics associated to skyrmions appearing as excitations on curved surfaces. Using a continuum model we show that the presence of cylindrically radial and azimuthal fields destabilize the skyrmions that appear in the absence of an external field. Weak fields generate fractional skyrmions while strong magnetic fields yield stable 2π-skyrmions, which have their widths diminished by the magnetic field strength. Under azimuthal fields vortex appears as stable state on the curved surface. - Highlights: • Stability of skyrmions on curved surfaces in the presence of a magnetic field. • Weak fields can destabilize skyrmions. • Strong magnetic fields yield the appearing of 2π-skyrmions. • The width of skyrmions is determined by the curvature and magnetic field strength. • Under azimuthal fields vortex appears as stable states.

Single-photon ionization is one of the most fundamental light matter interactions in nature, serving as a universal probe of the quantum state of matter. By probing the emitted electron, one can decode the full dynamics of the interaction. When photo-ionization is evolving in the presence of a strong laser field, the fundamental properties of the mechanism can be signicantly altered. Here we demonstrate how the liberated electron can perform a self-probing measurement of such interaction with attosecond precision. Extreme ultraviolet attosecond pulses initiate an electron wavepacket by photo-ionization, a strong infrared field controls its motion, and finally electron-ion collision maps it into re-emission of attosecond radiation bursts. Our measurements resolve the internal clock provided by the self-probing mechanism, obtaining a direct insight into the build-up of photo-ionization in the presence of the strong laser field.

Sensitivity analysis of uranium solubility under strongly oxidizing conditions

International Nuclear Information System (INIS)

Liu, L.; Neretnieks, I.

1999-01-01

To evaluate the effect of geochemical conditions in the repository on the solubility of uranium under strongly oxidizing conditions, a mathematical model has been developed to determine the solubility, by utilizing a set of nonlinear algebraic equations to describe the chemical equilibria in the groundwater environment. The model takes into account the predominant precipitation-dissolution reactions, hydrolysis reactions and complexation reactions that may occur under strongly oxidizing conditions. The model also includes the solubility-limiting solids induced by the presence of carbonate, phosphate, silicate, calcium, and sodium in the groundwater. The thermodynamic equilibrium constants used in the solubility calculations are essentially taken from the NEA Thermochemical Data Base of Uranium, with some modification and some uranium minerals added, such as soddyite, rutherfordite, uranophane, uranyl orthophosphate, and becquerelite. By applying this model, the sensitivities of uranium solubility to variations in the concentrations of various groundwater component species are systematically investigated. The results show that the total analytical concentrations of carbonate, phosphate, silicate, and calcium in deep groundwater play the most important role in determining the solubility of uranium under strongly oxidizing conditions

Interaction of a strong vortex with decaying turbulence

Terry, P.W.

1988-01-01

The evolution of a localized, axially symmetric vortex under the action of shear stresses associated with decaying two-dimensional turbulent vorticity which is inhomogeneous in the presence of the vortex is studied analytically. For a vortex which is sufficiently strong relative to the coefficient of turbulent eddy viscosity, it is shown that turbulent fluctuations in the vortex interior and diffusion of coherent vorticity by the turbulence localize to the vortex periphery. It is also found that the coefficient of diffusion is small compared to the coefficient of eddy viscosity. 8 refs

Comparative federal health care policy: evidence of collaborative federalism in Pakistan and Venezuela.

Science.gov (United States)

Baracskay, Daniel

2013-01-01

Collaborative federalism has provided an effective analytical foundation for understanding how complex public policies are implemented in federal systems through intergovernmental and intersectoral alignments. This has particularly been the case in issue areas like public health policy where diseases are detected and treated at the local level. While past studies on collaborative federalism and health care policy have focused on federal systems that are largely democratic, little research has been conducted to examine the extent of collaboration in authoritarian structures. This article applies the collaborative federalism approach to the Islamic Republic of Pakistan and the Bolivarian Republic of Venezuela. Evidence suggests that while both nations have exhibited authoritarian governing structures, there have been discernible policy areas where collaborative federalism is embraced to facilitate the implementation process. Further, while not an innate aspect of their federal structures, Pakistan and Venezuela can potentially expand their use of the collaborative approach to successfully implement health care policy and the epidemiological surveillance and intervention functions. Yet, as argued, this would necessitate further development of their structures on a sustained basis to create an environment conducive for collaborative federalism to flourish, and possibly expand to other policy areas as well.

Cigarette smoking and federal black lung benefits in bituminous coal miners.

Roy, T M; Collins, L C; Snider, H L; Anderson, W H

1989-02-01

The records of 1000 consecutive coal miners applying for benefits under the Federal Coal Mine Health and Safety Act were examined to determine the contribution of age, dust accumulation, and cigarette smoking to the profile of the miner who satisfies the current pulmonary criteria for disability. Using the presence of pneumoconiosis on chest radiograph as the indication of significant coal dust accumulation, the miners were separated into Group A--those without pneumoconiosis (n = 316) and Group B--those with pneumoconiosis (n = 684). The federal spirometric criteria for disability identified 55/316 miners in Group A (14.5%) and 99/684 miners in Group B (17.4%) potentially eligible for an award (P = .27). The mean ages of miners in both groups did not differ significantly, nor was there difference in the mean ages of groups that did or did not meet the federal criteria. In both groups, those miners potentially eligible for a financial award smoked more cigarettes than did their counterparts (Group A, 31.0 v 18.5 pack-years, P less than .001; Group B, 31.3 v 23.6 pack-years, P less than .001). There was no difference in the smoking histories of the miners from either group who met the federal criteria. Our data indicate that, in the case of bituminous coal miners, the present federal legislation intended to identify and remunerate those who suffer lung impairment from chronic occupational exposure to coal dust is biased in favor of those who sustain additional damage to their ventilatory capacity by smoking cigarettes.

Solidarity liability of federative entities and “side effects” for the right to health

Directory of Open Access Journals (Sweden)

Felipe Asensi

2016-02-01

Full Text Available The judicial enforcement of the right to health in Brazil raises advances and challenges for public policies. This article analyzes two judicial decisions from the 4th Region’s Federal Court in 2014 admitting the concurrent and solidary responsibility of federative entities in the supply of medicines. In both decisions, the appeal was allowed and the idea that federative entities have concurrent competence and solidarity in health was reinforced. On the one hand, a common example of interaction between the law and the health is observed in these decisions; on the other, a production of tensions and contradictions is identified. At first glance, the recognition of the solidary responsibility of federative entities may seem strongly positive from the user’s perspective, and this will lead to having more users going to courts to claim their right to health. However, from a management perspective, it brings challenges as there will be overpayment of some entities of the federation at the expense of others. In this sense, and based on cases, the main rules of competence currently used in health public policies will be presented. Major advances, limits and challenges of recognizing the solidary responsibility of federative entities as well as some “side effects” that some court decisions may bring will also be discussed.

Strong disorder RG approach of random systems

International Nuclear Information System (INIS)

Igloi, Ferenc; Monthus, Cecile

2005-01-01

There is a large variety of quantum and classical systems in which the quenched disorder plays a dominant ro-circumflex le over quantum, thermal, or stochastic fluctuations: these systems display strong spatial heterogeneities, and many averaged observables are actually governed by rare regions. A unifying approach to treat the dynamical and/or static singularities of these systems has emerged recently, following the pioneering RG idea by Ma and Dasgupta and the detailed analysis by Fisher who showed that the Ma-Dasgupta RG rules yield asymptotic exact results if the broadness of the disorder grows indefinitely at large scales. Here we report these new developments by starting with an introduction of the main ingredients of the strong disorder RG method. We describe the basic properties of infinite disorder fixed points, which are realized at critical points, and of strong disorder fixed points, which control the singular behaviors in the Griffiths-phases. We then review in detail applications of the RG method to various disordered models, either (i) quantum models, such as random spin chains, ladders and higher dimensional spin systems, or (ii) classical models, such as diffusion in a random potential, equilibrium at low temperature and coarsening dynamics of classical random spin chains, trap models, delocalization transition of a random polymer from an interface, driven lattice gases and reaction diffusion models in the presence of quenched disorder. For several one-dimensional systems, the Ma-Dasgupta RG rules yields very detailed analytical results, whereas for other, mainly higher dimensional problems, the RG rules have to be implemented numerically. If available, the strong disorder RG results are compared with another, exact or numerical calculations

1995-11-01

The Energy Information Administration (EIA) of the US Department of Energy (DOE) is mandated by Congress to be the agency that collects, analyzes, and disseminates impartial, comprehensive data about energy including the volume consumed, its customers, and the purposes for which it is used. The Federal Buildings Supplemental Survey (FBSS) was conducted by EIA in conjunction with DOE`s Office of Federal Energy Management Programs (OFEMP) to gain a better understanding of how Federal buildings use energy. This report presents the data from 881 completed telephone interviews with Federal buildings in three Federal regions. These buildings were systematically selected using OFEMP`s specifications; therefore, these data do not statistically represent all Federal buildings in the country. The purpose of the FBSS was threefold: (1) to understand the characteristics of Federal buildings and their energy use; (2) to provide a baseline in these three Federal regions to measure future energy use in Federal buildings as required in EPACT; and (3) to compare building characteristics and energy use with the data collected in the CBECS.

Opportunities and Prospects of Trade Development between Romania and the Russian Federation in the European Context

2010-10-01

Full Text Available The present paper has as main objective the analysis of the opportunities and development perspectives of the trade relationship between Romania and the Russian Federation, linked to the latest evolutions of the European and global economic context. Keeping in mind this objective, our paper is structured around three main sections, as follows. The first part, “Economic Context of Romania-Russian Federation Trade Development” is centered upon the global crisis and its effects on the EU, Romania and Russia as well as the EU-Russia increasing bilateral merchandise trade flows. We examine how the global economic crisis interrupted increasing merchandise trade between EU-27 and the Russian Federation and present the main exporter countries from the EU-27 to Russia and the major EU importers from Russia and analyze in a comparative manner the very concentrated trade pattern between EU-27 and Russia. In the next section, “Romania-Russia Trade Development”, we underline that the Russian Federation is the second extra-EU trading partner of our country. We explore Romania’s trade relationship with Russia during pre and post accession to the European Union and also the actual trends of the bilateral trade, which pattern is extremely concentrated. In the last section, “Opportunities and Prospects for the Trade Development between Romania and Russian Federation”, we conclude, on the basis of the comparative and prospective analysis, that: Romania could be well positioned on Russian markets; there are many similarities in competitiveness characteristics of our countries; Romania and Russia have some problematic factors in doing business; strong points of the Romanian manufacturing industry could lead to the diversification of trade pattern and, finally, Romania has the possibility to develop a strong economic partnership with the Russian Federation under the framework of the EU-Russia relationship.

Strongly correlated states of a small cold-atom cloud from geometric gauge fields

2011-01-01

Using exact diagonalization for a small system of cold bosonic atoms, we analyze the emergence of strongly correlated states in the presence of an artificial magnetic field. This gauge field is generated by a laser beam that couples two internal atomic states, and it is related to Berry's geometrical phase that emerges when an atom follows adiabatically one of the two eigenstates of the atom-laser coupling. Our approach allows us to go beyond the adiabatic approximation, and to characterize the generalized Laughlin wave functions that appear in the strong magnetic-field limit.

Nuclear supervision - Administration by the federal states on behalf of the Federal Government or direct federal administration? Evaluation from a practical point of view

International Nuclear Information System (INIS)

Cloosters, W.

2005-01-01

The organization of supervisory authorities under the Atomic Energy Act is not a new issue. In fact, it was discussed vehemently in the Federal Republic of Germany as far back as in the early fifties. Federal legislation in late 1959 decided to have the Atomic Energy Act executed in part under direct federal responsibility and, as far as the important supervision of the nuclear power plants operated in the Federal Republic of Germany was concerned, by the federal states on behalf of the federal government. Federal Minister for the Environment Trittin reopened the debate about the organization of nuclear administration by announcing his intention to transfer the supervision of nuclear power plants to direct federal administration. This announcement not only raises the question of legal permissibility of transferring nuclear power plant oversight to federal administration, but also requires a critical review, as presented in this article, of practical regulatory supervision to ensure safe operation of nuclear facilities. In this connection, both the actual content of supervisory activities and the way in which they are carried out must be examined in an effort to find an answer based on solid premises to the question raised above. For reasons explained in the contribution, oversight of nuclear power plants cannot be carried out as a centralized function. Instead, the legislative decision of 1959 in favor of the federal states exercising supervision on behalf of the federal government continues to be correct at the present stage also in the light of the steps initiated to opt out of the peaceful uses of nuclear power.

A comprehensive study of exponential-rigid-rotor equilibria for strong electron and ion rings indicates the presence of a sizeable percentage of untrapped particles in all equilibria with aspect-ratios R/a approximately <4. Such aspect-ratios are required in fusion-relevant rings. Significant changes in the equilibria are observed when untrapped particles are excluded by the use of a truncated exponential-rigid-rotor distribution function. (author)

FEDERAL AND REGIONAL CLUSTER POLICY OF THE RUSSIAN FEDERATION

Directory of Open Access Journals (Sweden)

Markov L. S.

2017-12-01

Full Text Available The article reviews the history of cluster policy in Russia at the federal and regional levels. The federal cluster policy is realized in three directions, studying which allowed us to outline the main features of a formalized cluster that claims state support. The trend of reorientation of the cluster policy from supporting clusters and their infrastructure to cluster projects is revealed. Systematization and comparative analysis of the cluster policy in the regions of the country leading in terms of cluster development is carried out. It is established that the regional cluster policy is at a nascent stage and is a projection of the federal programs. At the regional level, there is no institutional basis for the cluster policy in Russia. The regional cluster policy is characterized by homogeneity of organizational structures.

A new class of strongly coupled plasmas inspired by sonoluminescence

Science.gov (United States)

Bataller, Alexander; Plateau, Guillaume; Kappus, Brian; Putterman, Seth

2014-10-01

Sonoluminescence originates in a strongly coupled plasma with a near liquid density and a temperature of ~10,000 K. This plasma is in LTE and therefore, it should be a general thermodynamic state. To test the universality of sonoluminescence, similar plasma conditions were generated using femtosecond laser breakdown in high pressure gases. Calibrated streak spectroscopy reveals both transport and thermodynamic properties of a strongly coupled plasma. A blackbody spectrum, which persists long after the exciting laser has turned off, indicates the presence of a highly ionized LTE microplasma. In parallel with sonoluminescence, this thermodynamic state is achieved via a considerable reduction in the ionization potential. We gratefully acknowledge support from DARPA MTO for research on microplasmas. We thank Brian Naranjo, Keith Weninger, Carlos Camara, Gary Williams, and John Koulakis for valuable discussions.

Strong transthyretin immunostaining: potential pitfall in cardiac amyloid typing.

Although systemic amyloidosis commonly presents with renal disease, cardiac involvement usually determines the patient's prognosis. Cardiac involvement is seen in light chain amyloid and transthyretin amyloidosis. Distinguishing between these two is critical because prognosis and treatment differ. Our study demonstrates the unreliability of transthyretin immunostaining in subtyping cardiac amyloid. Between January 2003 and August 2010, we retrieved 229 native endomyocardial biopsies, of which 24 had amyloid. Immunohistochemistry for κ, λ, transthyretin, and serum amyloid A protein was performed on formalin-fixed, paraffin-embedded sections. Staining was graded as weak (trace to 1+) or strong (2 to 3+). Mass spectrometry (MS)-based proteomic typing of microdissected amyloid material was performed on selected cases. Fifteen patients had monoclonal gammopathy/plasma cell dyscrasia with cardiac amyloid. Eight of them (53%) showed strong transthyretin staining in the cardiac amyloid deposits. MS was performed in 5 of these 8 biopsies, and all 5 biopsies revealed light chain amyloid-type amyloid. Two of these 5 light chain amyloid biopsies did not even have concomitant strong staining for the appropriate light chain. Among the 15 cases with plasma cell dyscrasia, only 7 biopsies showed strong staining for the corresponding monoclonal light chain. Strong, false-positive immunostaining for transthyretin in cardiac amyloid is a potential pitfall, augmented by the frequent lack of staining for immunoglobulin light chains. Therefore, the presence of amyloid in the cardiac biopsy should prompt a search for plasma cell dyscrasia irrespective of transthyretin staining. Confirmation with MS should be sought, particularly if there is any discrepancy between κ/λ staining and serum immunofixation results.

We utilize an exact quantum calculation to explore axion emission from electrons and protons in the presence of the strong magnetic field of magnetars. The axion is emitted via transitions between the Landau levels generated by the strong magnetic field. The luminosity of axions emitted by protons is shown to be much larger than that of electrons and becomes stronger with increasing matter density. Cooling by axion emission is shown to be much larger than neutrino cooling by the Urca processes. Consequently, axion emission in the crust may significantly contribute to the cooling of magnetars. In the high-density core, however, it may cause heating of the magnetar.

Angular-momentum-assisted dissociation of CO in strong optical fields

Filaments are produced in CO gas by intense, chirped laser pulses. Visible emission from C2 is observed as a result of chemical reactions of highly excited CO. At laser intensities greater than 1014 W cm-2, the C2 emission shows a strong dependence on laser polarization. Oppositely chirped pulses of light with ω0 = 800 nm are recombined spatially and temporally to generate angularly accelerating electric fields (up to 30 THz) that either have an instantaneous linear polarization or act as a dynamic polarization grating that oscillates among linear and circular polarizations. The angularly accelerating linear polarization corresponds to an optical centrifuge that concurrently drives molecules into high rotational states (with J 50) and induces strong-field dissociation. Higher order excitation is observed for the time-varying laser polarization configuration that does not induce rotational excitation. The results indicate that the presence of rotational angular momentum lowers the threshold for CO dissociation in strong optical fields by coupling nuclear and electronic degrees of freedom.

Richard Weaver's Untraditional Case for Federalism

OpenAIRE

2004-01-01

Although Richard M. Weaver's political writings do not offer a systematic examination of federalism, they include a defense of federalist arrangements. Because Weaver's federalism is central to his conservatism, and because his argument for federalism differs from more common conservative defenses of federalism offered in the twentieth century, his writings allow students of federalism to examine possible connections between federalism and conservative political thought.

Anisotropy of the magnetoviscous effect in a cobalt ferrofluid with strong interparticle interaction

Energy Technology Data Exchange (ETDEWEB)

Linke, J.M., E-mail: julia.linke@tu-dresden.de; Odenbach, S.

2015-12-15

The anisotropy of the magnetoviscous effect (MVE) of a cobalt ferrofluid has been studied in a slit die viscometer for three orientations of the applied magnetic field: in the direction of the fluid flow (Δη{sub 1}), the velocity gradient (Δη{sub 2}), and the vorticity (Δη{sub 3}). The majority of the cobalt particles in the ferrofluid exhibit a strong dipole–dipole interaction, which corresponds to a weighted interaction parameter of λ{sub w}≈10.6. Thus the particles form extended microstructures inside the fluid which lead to enhanced MVE ratios Δη{sub 2}/Δη{sub 1}>3 and Δη{sub 3}/Δη{sub 1}>0.3 even for strong shearing and weak magnetic fields compared to fluids which contain non-interacting spherical particles with Δη{sub 2}/Δη{sub 1}≈1 and Δη{sub 3}/Δη{sub 1}=0. Furthermore, a non-monotonic increase has been observed in the shear thinning behavior of Δη{sub 2} for weak magnetic fields <10 kA/m, which cannot be explained solely by the magnetization of individual particles and the formation and disintegration of linear particle chains but indicates the presence of heterophase structures. - Highlights: • The magnetoviscous effect in a ferrofluid with strong interaction is anisotropic. • The strongest effects are found in a magnetic field parallel to the shear gradient. • In strong magnetic fields the microstructure of the fluid is stable against shearing. • In weak fields the fluid behavior indicates the presence of heterophase structures.

The Bekenstein bound in strongly coupled O(N) scalar field theory

We discuss the O(N) self-interacting scalar field theory, in the strong-coupling regime and also in the limit of large N. Considering that the system is in thermal equilibrium with a reservoir at temperature β -1 , we assume the presence of macroscopic boundaries conning the field in a hypercube of side L. Using the strong-coupling perturbative expansion, we generalize previous results, i.e., we obtain the renormalized mean energy E and entropy S for the system in rst order of the strong-coupling perturbative expansion, presenting an analytical proof that the specific entropy also satisfies in some situations a quantum bound. When considering the low temperature behavior of the specific entropy, the sign of the renormalized zero-point energy can invalidate this quantum bound. If the renormalized zero point-energy is a positive quantity, at intermediate temperatures and in the low temperature limit, there is a quantum bound. (author)

Inner-shell photoionization in weak and strong radiation fields

The X-ray beams presently produced at synchrotron-radiation facilities interact weakly with matter, and the observation of double photoionization is due to electron-electron interactions. The intensities of future X-ray free-electron lasers are expected to produce double photoionization by absorption of two photons. The example of double K-shell photoionization of neon is discussed in the one- and two-photon cases. We also describe an experiment in which X rays photoionize the K shell of krypton in the presence of a strong AC field imposed by an optical laser

Technetium and iodine aqueous species immobilization and transformations in the presence of strong reductants and calcite-forming solutions: Remedial action implications

At the Hanford Site in southeastern Washington State, radionuclide (Tc-99/I-129) laden liquid wastes have been discharged to ground, resulting in vadose zone contamination, which provides a continuous source of these contaminants to groundwater. The presence of multiple contaminants increases the complexity of finding viable remediation technologies to sequester vadose zone contaminants in situ and protect groundwater. Although previous studies have shown the efficiency of zero valent iron (ZVI) and sulfur modified iron (SMI) in reducing mobile Tc(VII) to immobile Tc(IV) and iodate incorporation into calcite, the coupled effects from simultaneously using these remedial technologies have not been previously studied. In this first-of-a-kind laboratory study, we used two efficient reductants (i.e., ZVI and SMI) and calcite-forming solutions to simultaneously remove aqueous Tc(VII) and iodate via reduction and incorporation, respectively. The results confirmed that Tc(VII) was rapidly removed from the aqueous phase via reduction to Tc(IV). ZVI removed Tc(VII) faster than SMI, although both had removed the same amount by the end of the experiments. Most of the aqueous iodate was rapidly transformed to iodide, and therefore was not incorporated into calcite, but instead remained in the aqueous phase. The iodate reduction to iodide was much faster than iodate incorporation into calcite, suggesting that this remedial pathway is not efficient in removing aqueous iodate when strong reductants are present. Other experiments suggested that iodate removal via calcite precipitation should occur first and then reductants should be added for Tc(VII) removal. Although ZVI can negatively impact microbial populations and thereby inhibit natural attenuation mechanisms, only changes in the makeup of the microbial community were observed. However, these changes in the microbial community may have an impact on remediation efforts in the long term that could not be seen in a short

Predictors of trust in the general science and climate science research of US federal agencies.

In this article, we focus on a key strategic objective of scientific organizations: maintaining the trust of the public. Using data from a nationally representative survey of American adults ( n = 1510), we assess the extent to which demographic factors and political ideology are associated with citizens' trust in general science and climate science research conducted by US federal agencies. Finally, we test whether priming individuals to first consider agencies' general science research influences trust in their climate science research, and vice versa. We found that federal agencies' general science research is more trusted than their climate science research-although a large minority of respondents did not have an opinion-and that political ideology has a strong influence on public trust in federal scientific research. We also found that priming participants to consider general scientific research does not increase trust in climate scientific research. Implications for theory and practice are discussed.

Information Asymmetry in Federations

Directory of Open Access Journals (Sweden)

Alexander Mikhailovich Libman

2014-12-01

Full Text Available The paper investigates the problems of information transmission between levels of government in a federal state. The central government in a federation typically faces serious difficulties while collecting information on economic and political situation in the regions. There are two types of problems: lack of incentives for the regions to accurately collect information and strategic manipulation of information, which are discussed in the paper along with possible solutions. In particular, overcoming information asymmetry would require the development of national parties or informal coalitions of bureaucrats and politicians of the center and of the regions, creating incentives for regional politicians to back the successful functioning of the federal level. Furthermore, the paper discusses the issue of «informal decentralization», which emerges as a result of information asymmetry, and its consequences for the functioning of a federal state, including both advantages and disadvantages. We conclude that under information asymmetry the organization of the federation will inevitably turn into an issue of permanent negotiations and bargaining between the center and the regions, which functions as the information acquisition tool for optimal allocation of authorities in a federation

The Electron-Phonon Interaction in Strongly Correlated Systems

International Nuclear Information System (INIS)

Castellani, C.; Grilli, M.

1995-01-01

We analyze the effect of strong electron-electron repulsion on the electron-phonon interaction from a Fermi-liquid point of view and show that the electron-electron interaction is responsible for vertex corrections, which generically lead to a strong suppression of the electron-phonon coupling in the v F q/ω >>1 region, while such effect is not present when v F q/ω F is the Fermi velocity and q and ω are the transferred momentum and frequency respectively. In particular the e-ph scattering is suppressed in transport properties which are dominated by low-energy-high-momentum processes. On the other hand, analyzing the stability criterion for the compressibility, which involves the effective interactions in the dynamical limit, we show that a sizable electron-phonon interaction can push the system towards a phase-separation instability. Finally a detailed analysis of these ideas is carried out using a slave-boson approach for the infinite-U three-band Hubbard model in the presence of a coupling between the local hole density and a dispersionless optical phonon.

We report new multi-spacecraft Cluster observations of tripolar guide magnetic field perturbations at a solar wind reconnection exhaust in the presence of a guide field B{sub M} {sub  }which is almost four times as strong as the reversing field B{sub L}. The novel tripolar field consists of two narrow regions of depressed B{sub M}, with an observed 7%–14% ΔB{sub M} magnitude relative to the external field, which are found adjacent to a wide region of enhanced B{sub M} within the exhaust. A stronger reversing field is associated with each B{sub M} depression. A kinetic reconnection simulation for realistic solar wind conditions and the observed strong guide field reveals that tripolar magnetic fields preferentially form across current sheets in the presence of multiple X-lines as magnetic islands approach one another and merge into fewer and larger islands. The simulated ΔB{sub M}/ΔX{sub N} over the normal width ΔX{sub N} between a B{sub M} minimum and the edge of the external region agree with the normalized values observed by Cluster. We propose that a tripolar guide field perturbation may be used to identify candidate regions containing multiple X-lines and interacting magnetic islands at individual solar wind current sheets with a strong guide field.

Pion Production from Proton Synchrotron Radiation under Strong Magnetic Field in Relativistic Quantum Approach

2016-01-01

Full Text Available We study pion production from proton synchrotron radiation in the presence of strong magnetic fields by using the exact proton propagator in a strong magnetic field and explicitly including the anomalous magnetic moment. Results in this exact quantum-field approach do not agree with those obtained in the semi-classical approach. Furthermore, we also find that the anomalous magnetic moment of the proton greatly enhances the production rate about by two orders of magnitude, and that the polar angle of an emitted pion is the same as that of an initial proton.

Semicalssical quantization of interacting anyons in a strong magnetic field

Levit, S.; Sivan, N.

1992-01-01

We represent a semiclassical theory of charged interacting anyons in strong magnetic fields. We apply this theory to a number of few anyons systems including two interacting anyons in the presence of an impurity and three interacting anyons. We discuss the dependence of their energy levels on the statistical parameter and find regions in which this dependence follows very different patterns. The semiclassical arguments allow to correlate these patterns with the change in the character of the classical motion of the system. (author)

Optimization of the LCLS X-Rray FEL Output Performance in the Presence of Strong Undulator Wakefields

2005-01-01

The Linac Coherent Light Source (LCLS) Free-Electron Laser will operate in the wavelength range of 1.5 to 15 Angstroms. Energy loss due to wakefields within the long undulator can degrade the FEL process by detuning the resonant FEL frequency. The wakefields arise from the vacuum chamber wall resistivity, its surface roughness, and abrupt changes in its aperture. For LCLS parameters, the resistive component is the most critical and depends upon the chamber material (e.g. Cu) and its radius. To study the expected performance in the presence of these wakefields, we make a series of "start-to-end" simulations with tracking codes PARMELA and ELEGANT and time-dependent FEL simulation codes Genesis 1.3 and Ginger. We discuss the impact of the wakefield on output energy, spectral bandwidth, and temporal envelope of the output FEL pulse, as well as the benefits of a partial compensation obtained with a slight z dependent taper in the undulator field. We compare these results to those obtained by decreasing the bunch ...

Strong water absorption in the dayside emission spectrum of the planet HD 189733b.

Recent observations of the extrasolar planet HD 189733b did not reveal the presence of water in the emission spectrum of the planet. Yet models of such 'hot-Jupiter' planets predict an abundance of atmospheric water vapour. Validating and constraining these models is crucial to understanding the physics and chemistry of planetary atmospheres in extreme environments. Indications of the presence of water in the atmosphere of HD 189733b have recently been found in transmission spectra, where the planet's atmosphere selectively absorbs the light of the parent star, and in broadband photometry. Here we report the detection of strong water absorption in a high-signal-to-noise, mid-infrared emission spectrum of the planet itself. We find both a strong downturn in the flux ratio below 10 microm and discrete spectral features that are characteristic of strong absorption by water vapour. The differences between these and previous observations are significant and admit the possibility that predicted planetary-scale dynamical weather structures may alter the emission spectrum over time. Models that match the observed spectrum and the broadband photometry suggest that heat redistribution from the dayside to the nightside is weak. Reconciling this with the high nightside temperature will require a better understanding of atmospheric circulation or possible additional energy sources.

Aspects of the formation and equilibration of a quark-gluon plasma are explored using a quantum kinetic equation, which involves a non-Markovian, Abelian source term for quark and antiquark production and, for the collision term, a relaxation time approximation that defines a time-dependent quasi-equilibrium temperature and collective velocity. The strong Abelian field is determined via the simultaneous solution of Maxwell's equation. A particular feature of this approach is the appearance of plasma oscillations in all thermodynamic observables. Their presence can lead to a sharp increase in the time-integrated dilepton yield, although a rapid expansion of the plasma may eliminate this signal. (orig.)

Towards TDDFT for Strongly Correlated Materials

Directory of Open Access Journals (Sweden)

Shree Ram Acharya

2016-09-01

Full Text Available We present some details of our recently-proposed Time-Dependent Density-Functional Theory (TDDFT for strongly-correlated materials in which the exchange-correlation (XC kernel is derived from the charge susceptibility obtained using Dynamical Mean-Field Theory (the TDDFT + DMFT approach. We proceed with deriving the expression for the XC kernel for the one-band Hubbard model by solving DMFT equations via two approaches, the Hirsch–Fye Quantum Monte Carlo (HF-QMC and an approximate low-cost perturbation theory approach, and demonstrate that the latter gives results that are comparable to the exact HF-QMC solution. Furthermore, through a variety of applications, we propose a simple analytical formula for the XC kernel. Additionally, we use the exact and approximate kernels to examine the nonhomogeneous ultrafast response of two systems: a one-band Hubbard model and a Mott insulator YTiO3. We show that the frequency dependence of the kernel, i.e., memory effects, is important for dynamics at the femtosecond timescale. We also conclude that strong correlations lead to the presence of beats in the time-dependent electric conductivity in YTiO3, a feature that could be tested experimentally and that could help validate the few approximations used in our formulation. We conclude by proposing an algorithm for the generalization of the theory to non-linear response.

Strong asymmetry for surface modes in nonlinear lattices with long-range coupling

International Nuclear Information System (INIS)

Martinez, Alejandro J.; Vicencio, Rodrigo A.; Molina, Mario I.

2010-01-01

We analyze the formation of localized surface modes on a nonlinear cubic waveguide array in the presence of exponentially decreasing long-range interactions. We find that the long-range coupling induces a strong asymmetry between the focusing and defocusing cases for the topology of the surface modes and also for the minimum power needed to generate them. In particular, for the defocusing case, there is an upper power threshold for exciting staggered modes, which depends strongly on the long-range coupling strength. The power threshold for dynamical excitation of surface modes increases (decreases) with the strength of long-range coupling for the focusing (defocusing) cases. These effects seem to be generic for discrete lattices with long-range interactions.

We explore various aspects of the motion of heavy quarks in strongly-coupled gauge theories, employing the AdS/CFT correspondence. Building on earlier work by Mikhailov, we study the dispersion relation and energy loss of an accelerating finite-mass quark in N=4 super-Yang-Mills, both in vacuum and in the presence of a thermal plasma. In the former case, we notice that the application of an external force modifies the dispersion relation. In the latter case, we find in particular that when a ...

Crossover in tunneling hops in systems of strongly localized electrons

1995-11-01

Accurate Monte-Carlo simulation data show a consistent crossover in different characters of tunneling hops in two-dimensional systems of strongly localized electrons in the presence of scattering and quantum interference of hopping paths. The results also suggest a negative answer to the question whether there is a two-dimensional sign phase transition. The fractal behaviour observed in the direction perpendicular to the hopping direction is found to be similar to that for eigenstates in one-dimensional localized systems. (author). 16 refs, 6 figs

Thermally activated flux creep in strongly layered high-temperature superconductors

Thermal activation energies for single vortices and vortex bundles in the presence of a magnetic field parallel to the layers are calculated. The pinning considered is intrinsic and is due to the strongly layered structure of high-temperature superconductors. The magnetic field and the current dependence of the activation energy are studied in detail. The calculation of the activation energy is used to determine the current-voltage characteristic. It may be possible to observe the effects discussed in this paper in a pure enough sample

1979-01-01

Today's situation of nuclear energy is strongly influenced by political decisions often initiated by arguments in a public discussion with little rational background. This needs to be contrasted by a nuclear development strategy taking into account the long term needs of the Federal Republic of Germany. In the light of the situation at present a strategy would emerge which is based on the continuous use of and a moderate but steady increase in the number of light water reactors. Also high temperature reactors must find a well-defined position. However, a key role must be assigned to fast breeder reactors, unless the whole concept is to be endangered. (orig.) [de

Dynamics of Rydberg atom lattices in the presence of noise and dissipation

International Nuclear Information System (INIS)

Abdussalam, Wildan

2017-01-01

The work presented in this dissertation concerns dynamics of Rydberg atom lattices in the presence of noise and dissipation. Rydberg atoms possess a number of exaggerated properties, such as a strong van der Waals interaction. The interplay of that interaction, coherent driving and decoherence leads to intriguing non-equilibrium phenomena. Here, we study the non-equilibrium physics of driven atom lattices in the presence of decoherence caused by either laser phase noise or strong decay. In the first case, we compare between global and local noise and explore their effect on the number of excitations and the full counting statistics. We find that both types of noise give rise to a characteristic distribution of the Rydberg excitation number. The main method employed is the Langevin equation but for the sake of efficiency in certain regimes, we use a Markovian master equation and Monte Carlo rate equations, respectively. In the second case, we consider dissipative systems with more general power-law interactions. We determine the phase diagram in the steady state and analyse its generation dynamics using Monte Carlo rate equations. In contrast to nearest-neighbour models, there is no transition to long-range-ordered phases for realistic interactions and resonant driving. Yet, for finite laser detunings, we show that Rydberg atom lattices can undergo a dissipative phase transition to a long-range-ordered antiferromagnetic phase. We identify the advantages of Monte Carlo rate equations over mean field predictions. Having studied the dynamics of Rydberg atom lattices, we study an application of the strong interactions in such systems for quantum information processing. We investigate the coherent exchange of a single photon between a superconducting microwave cavity and a lattice of strongly interacting Rydberg atoms in the presence of local electric field fluctuations plaguing the cavity surface. We show that despite the increased sensitivity of Rydberg states to

We determine the phase diagram in the steady state and analyse its generation dynamics using Monte Carlo rate equations. In contrast to nearest-neighbour models, there is no transition to long-range-ordered phases for realistic interactions and resonant driving. Yet, for finite laser detunings, we show that Rydberg atom lattices can undergo a dissipative phase transition to a long-range-ordered antiferromagnetic phase. We identify the advantages of Monte Carlo rate equations over mean field predictions. Having studied the dynamics of Rydberg atom lattices, we study an application of the strong interactions in such systems for quantum information processing. We investigate the coherent exchange of a single photon between a superconducting microwave cavity and a lattice of strongly interacting Rydberg atoms in the presence of local electric field fluctuations plaguing the cavity surface. We show that despite the increased sensitivity of Rydberg states to

Full Text Available Background. The sense of presence is an important aspect of interaction with virtual reality applications. Earlier we suggested that presence can depend on cognitive control. The latter is a set of meta-cognitive processes which are responsible for configuring the cognitive system for the accomplishment of specific tasks with respect to a given context. In particular, cognitive control helps in preventing interference from the task-irrelevant variables. Objective. is study aimed at investigation of the possible relationship between interference control and aspects of presence. Design. Thirty-nine subjects (32 female and 7 male, aged 18 to 27 years participated in the study. The subjects were assessed via a battery of interference control tasks (Flanker Task, Go/No Go task, antisaccade task and performed a virtual scenario (navigating within an array of randomly placed virtual digits in correct numerical order in high-immersion (CAVE and low-immersion (standard computer display virtual environments. Afterwards, the subjects completed a Russian version of the ITC-Sense of Presence inventory. Results. We found that interference control is generally related to the sense of presence, especially in the CAVE (high-immersion environment. Sensory interference control was most strongly associated with various aspects of presence (overall presence score, spatial presence, and emotional involvement. Motor interference control was associated with spatial presence and emotional involvement, but this relationship was weaker than was the case with sensory interference control. Low-immersion virtual environments attenuate some of these links between interference control and presence so that only sensory interference control remains a notable predictor of presence. Conclusion. Interference control is positively associated with presence in virtual environments with varying immersion levels. is may reflect a more general cause-and-effect relationship between

Hadley, Donald L

2001-01-01

This Federal Technology Alert, which was sponsored by the U.S. Department of Energy's Office of Federal Energy Management Programs, provides the detailed information and procedures that a Federal energy manager needs to evaluate most ground-source heat pump applications. This report updates an earlier report on ground-source heat pumps that was published in September 1995. In the current report, general benefits of this technology to the Federal sector are described, as are ground-source heat pump operation, system types, design variations, energy savings, and other benefits. In addition, information on current manufacturers, technology users, and references for further reading are provided

2007-01-01

The dynamics of charge injection in silicon nanocrystals embedded in a silicon dioxide matrix is studied using electrostatic force microscopy. We show that the presence of silicon nanocrystals with a density of 10 11 cm -2 is essential for strong localization of charges, and results in exceptional charge retention properties compared to nanocrystal-free SiO 2 samples. In both systems, a logarithmic dependence of the diameter of the charged area on the injection time is experimentally observed on a timescale between 0.1 and 10 s (voltage≤10 V). A field-emission injection, limited by Coulomb blockade and a lateral charge spreading due to a repulsive radial electric field are used to model the sample charging. Once the tip is retracted, the electron cloud is strongly confined in the nanocrystals and remains static

New directions in federal energy management

The fuel embargo of 1973, followed by the oil disruption of 1979 heightened national security concerns over the availability and price of foreign oil to sustain all sectors of the U.S. economy. As a result of our growing dependence on foreign oil and diminishing resources at home, the Federal government has worked since 1974 to identify and implement a variety of measures to reduce energy consumption in Federal buildings and operations. Federal energy expenditures peaked at almost $14 billion in 1982 but has now been reduced to approximately $10 billion a year. However, much more needs to be done. Since the 1973 oil embargo, a series of legislative initiatives and Presidential authorities established the Federal Energy Management Program (FEMP) and then expanded it to address a broad range of energy-related issues affecting the Federal sector. Administered by the U.S. Department of Energy, FEMP coordinates the design and implementation of energy-saving programs for Federal buildings and operations. This includes working with other Federal agencies through interagency committees to interpret and implement Federal policy, to provide technical assistance to other Federal agencies, and to collect and report Federal energy consumption data to Congress. In addition, with the passage of the Clean Air Act Amendments of 1990, concerns over global climate change and a range of man-made and natural pollutants, environmental issues now play a critical role in our nation's energy policy. As a major consumer of energy, the Federal sector can serve as an important model for other sectors of the economy as a result of some of the innovative and cost-effective measures planned or currently underway. My talk today will focus on the Federal government's plans to ensure the energy efficient design and operation of Federal facilities, with an emphasis on life-cycle cost analyses

Renormalisation of Nonequilibrium Phonons Under Strong Perturbative Influences.

Science.gov (United States)

Mehta, Sushrut Madhukar

Effects of strong perturbative influences, namely the presence of a narrow distribution of acoustic phonons, and the presence of an electron plasma, on the dynamics of nonequilibrium, near zone center, longitudinal optical phonons in GaP have been investigated in two separate experiments. The study of the effects of the interaction between the LO phonons and a heavily populated, narrow distribution of acoustic phonons lead to the observation of a new optically driven nonequilibrium phonon state. Time Resolved Coherent Antistokes Raman Scattering (TR-CARS), with picosecond resolution, was used to investigate the new mode. In order to achieve high occupation numbers in the acoustic branch, the picosecond laser pulses used were amplified up to 1.0 GW/cm^2 peak power per laser beam. An important characteristic property of the new state which differentiates it from the well known LO phonon state is the fact that rather than having the single decay rate observed under thermal equilibrium, the new state has two decay rates. Moreover, these two decay rates depend strongly on the distribution of the acoustic phonon occupation number. The coupling of the LO phonons with an electron plasma, on the other hand, was investigated by measurements of the shape of the Raman scattered line associated with the phonon-plasmon coupled mode. The plasma was generated by thermal excitation of carriers in doped samples. It was possible to study a large variety of plasma excitations by controlling the concentration of the dopant and the ambient temperature. A complete, self consistant model based on standard dielectric response theory is presented, and applied to the measurements of the phonon-plasmon coupled mode. It is possible to recover, via this model, the effective coupled mode damping rate, the plasma damping rate, and the plasma frequency as functions of ambient temperature, or the carrier concentration.

The politics of harm reduction in federal prisons.

Science.gov (United States)

Watson, Tara Marie

2014-09-01

We need to understand better the political barriers to prison-based harm reduction programs. In this paper, I examine the situation in the Correctional Service of Canada (CSC), a federal prison agency with a zero-tolerance drug policy and general opposition to prison needle and syringe programs (PNSPs) and safer tattooing initiatives. This study draws on 16 interviews with former CSC senior officials, former frontline staff, and external stakeholders; CSC policy and practice documents; and testimony from a House of Commons Standing Committee public study. Thematic coding and comparison of texts were used to examine emergent themes of interest. Four interrelated issues were central for understanding the political barriers: a narrower definition of harm reduction used in corrections, both in principle and practice; the Conservative government's tough-on-crime agenda; strong union opposition; and stakeholder perceptions that political constraints will likely persist, including the view that litigation may offer the only way to introduce PNSPs. The system is at an impasse and key questions remain about the importability of harm reduction services into federal prisons. Despite a highly challenging policy environment, moving forward will demand asking new, critical questions and devising more strategic ways of entering the political-operational dialogue that opposes evidence-based programs.

Nurse-midwives in federally funded health centers: understanding federal program requirements and benefits.

Science.gov (United States)

Carter, Martha

2012-01-01

Midwives are working in federally funded health centers in increasing numbers. Health centers provide primary and preventive health care to almost 20 million people and are located in every US state and territory. While health centers serve the entire community, they also serve as a safety net for low-income and uninsured individuals. In 2010, 93% of health center patients had incomes below 200% of the Federal Poverty Guidelines, and 38% were uninsured. Health centers, including community health centers, migrant health centers, health care for the homeless programs, and public housing primary care programs, receive grant funding and enjoy other benefits due to status as federal grantees and designation as federally qualified health centers. Clinicians working in health centers are also eligible for financial and professional benefits because of their willingness to serve vulnerable populations and work in underserved areas. Midwives, midwifery students, and faculty working in, or interacting with, health centers need to be aware of the regulations that health centers must comply with in order to qualify for and maintain federal funding. This article provides an overview of health center regulations and policies affecting midwives, including health center program requirements, scope of project policy, provider credentialing and privileging, Federal Tort Claims Act malpractice coverage, the 340B Drug Pricing Program, and National Health Service Corps scholarship and loan repayment programs. © 2012 by the American College of Nurse-Midwives.

Querying on Federated Sensor Networks

Directory of Open Access Journals (Sweden)

Zuhal Can

2016-09-01

Full Text Available A Federated Sensor Network (FSN is a network of geographically distributed Wireless Sensor Networks (WSNs called islands. For querying on an FSN, we introduce the Layered Federated Sensor Network (L-FSN Protocol. For layered management, L-FSN provides communication among islands by its inter-island querying protocol by which a query packet routing path is determined according to some path selection policies. L-FSN allows autonomous management of each island by island-specific intra-island querying protocols that can be selected according to island properties. We evaluate the applicability of L-FSN and compare the L-FSN protocol with various querying protocols running on the flat federation model. Flat federation is a method to federate islands by running a single querying protocol on an entire FSN without distinguishing communication among and within islands. For flat federation, we select a querying protocol from geometrical, hierarchical cluster-based, hash-based, and tree-based WSN querying protocol categories. We found that a layered federation of islands by L-FSN increases the querying performance with respect to energy-efficiency, query resolving distance, and query resolving latency. Moreover, L-FSN’s flexibility of choosing intra-island querying protocols regarding the island size brings advantages on energy-efficiency and query resolving latency.

Exact results relating spin-orbit interactions in two-dimensional strongly correlated systems

Science.gov (United States)

Kucska, Nóra; Gulácsi, Zsolt

2018-06-01

A 2D square, two-bands, strongly correlated and non-integrable system is analysed exactly in the presence of many-body spin-orbit interactions via the method of Positive Semidefinite Operators. The deduced exact ground states in the high concentration limit are strongly entangled, and given by the spin-orbit coupling are ferromagnetic and present an enhanced carrier mobility, which substantially differs for different spin projections. The described state emerges in a restricted parameter space region, which however is clearly accessible experimentally. The exact solutions are provided via the solution of a matching system of equations containing 74 coupled, non-linear and complex algebraic equations. In our knowledge, other exact results for 2D interacting systems with spin-orbit interactions are not present in the literature.

Comptonization in Ultra-Strong Magnetic Fields: Numerical Solution to the Radiative Transfer Problem

Science.gov (United States)

Ceccobello, C.; Farinelli, R.; Titarchuk, L.

2014-01-01

We consider the radiative transfer problem in a plane-parallel slab of thermal electrons in the presence of an ultra-strong magnetic field (B approximately greater than B(sub c) approx. = 4.4 x 10(exp 13) G). Under these conditions, the magnetic field behaves like a birefringent medium for the propagating photons, and the electromagnetic radiation is split into two polarization modes, ordinary and extraordinary, that have different cross-sections. When the optical depth of the slab is large, the ordinary-mode photons are strongly Comptonized and the photon field is dominated by an isotropic component. Aims. The radiative transfer problem in strong magnetic fields presents many mathematical issues and analytical or numerical solutions can be obtained only under some given approximations. We investigate this problem both from the analytical and numerical point of view, provide a test of the previous analytical estimates, and extend these results with numerical techniques. Methods. We consider here the case of low temperature black-body photons propagating in a sub-relativistic temperature plasma, which allows us to deal with a semi-Fokker-Planck approximation of the radiative transfer equation. The problem can then be treated with the variable separation method, and we use a numerical technique to find solutions to the eigenvalue problem in the case of a singular kernel of the space operator. The singularity of the space kernel is the result of the strong angular dependence of the electron cross-section in the presence of a strong magnetic field. Results. We provide the numerical solution obtained for eigenvalues and eigenfunctions of the space operator, and the emerging Comptonization spectrum of the ordinary-mode photons for any eigenvalue of the space equation and for energies significantly lesser than the cyclotron energy, which is on the order of MeV for the intensity of the magnetic field here considered. Conclusions. We derived the specific intensity of the

Strong field QED in lepton colliders and electron/laser interactions

Science.gov (United States)

Hartin, Anthony

2018-05-01

The studies of strong field particle physics processes in electron/laser interactions and lepton collider interaction points (IPs) are reviewed. These processes are defined by the high intensity of the electromagnetic fields involved and the need to take them into account as fully as possible. Thus, the main theoretical framework considered is the Furry interaction picture within intense field quantum field theory. In this framework, the influence of a background electromagnetic field in the Lagrangian is calculated nonperturbatively, involving exact solutions for quantized charged particles in the background field. These “dressed” particles go on to interact perturbatively with other particles, enabling the background field to play both macroscopic and microscopic roles. Macroscopically, the background field starts to polarize the vacuum, in effect rendering it a dispersive medium. Particles encountering this dispersive vacuum obtain a lifetime, either radiating or decaying into pair particles at a rate dependent on the intensity of the background field. In fact, the intensity of the background field enters into the coupling constant of the strong field quantum electrodynamic Lagrangian, influencing all particle processes. A number of new phenomena occur. Particles gain an intensity-dependent rest mass shift that accounts for their presence in the dispersive vacuum. Multi-photon events involving more than one external field photon occur at each vertex. Higher order processes which exchange a virtual strong field particle resonate via the lifetimes of the unstable strong field states. Two main arenas of strong field physics are reviewed; those occurring in relativistic electron interactions with intense laser beams, and those occurring in the beam-beam physics at the interaction point of colliders. This review outlines the theory, describes its significant novel phenomenology and details the experimental schema required to detect strong field effects and the

Although federal law grants patients the right to view and amend their medical records, few studies have proposed a process for patients to coauthor their subjective history in their medical record. Allowing patients to fully disclose and document their medical history is an important step to improve the diagnostic process. To evaluate patients' office experience before and after they authored their subjective medical history for the electronic health record. Patients were mailed a prehistory form and presurvey to be completed before their family medicine office visit. On arrival to the office, the prehistory form was scanned into the electronic health record while the content was transcribed by hospital staff into the appropriate fields in the history component of the encounter note. Postsurveys were given to patients to be completed after their visit. Pre- and postsurveys measured the patients' perception of office visit quality as well as completeness and accuracy of their electronic health record documentation before and after their appointment. Medical staff surveys were collected weekly to measure the staff's viewpoint of the federal law that allows patients to view and amend their medical records. Of 405 patients who were asked to participate, 263 patients aged 14 to 94 years completed a presurvey and a prehistory form. Of those 263 patients, 134 completed a postsurvey. The pre- and postsurveys showed improved patient satisfaction with the office visit and high scores for documentation accuracy and completeness. Before filling out the prehistory form, 116 of 249 patients (46.6%) agreed or strongly agreed that they felt more empowered in their health care by completing the prehistory form compared with 110 of 131 (84.0%) who agreed or strongly agreed after the visit (Pprehistory form beforehand to improve the patient experience while accommodating federal law.

The Relation between Virtual Presence and Learning Outcomes in Serious Games – The Mediating Effect of Motivation

Directory of Open Access Journals (Sweden)

Claudia Schrader

2014-02-01

Full Text Available Does the immersive design of a serious game affect learners’ virtual presence? Does virtual presence improve learning? By identifying virtual presence as a variable that may determine learning outcomes, it is argued that computer gaming environments present a new challenge for researchers to investigate. Particularly, the effect of games on virtual presence might help designers to predict which instructional configurations will maximize learning performance. Results indicate that the serious game used as an example in this study leads to a strong form of virtual presence. Virtual presence enhanced retention and comprehension but not transfer. It also significantly increased learners’ motivation. Mediation analyses report that the positive relation between virtual presence, retention and comprehension is mediated through increased motivation. These findings suggest that the relation between all variables should be considered an important factor in the design of virtual worlds for learning.

The consideration of possible neutron Lloyd's mirror interferometer experiment to search for strongly coupled chameleon fields is presented. The chameleon scalar fields were proposed to explain the acceleration of expansion of the Universe. The presence of a chameleon field results in a change of a particle's potential energy in vicinity of a massive body. This interaction causes a phase shift of neutron waves in the interferometer. The sensitivity of the method is estimated

A Framework for Federated Two-Factor Authentication Enabling Cost-Effective Secure Access to Distributed Cyberinfrastructure

Energy Technology Data Exchange (ETDEWEB)

Ezell, Matthew A [ORNL; Rogers, Gary L [University of Tennessee, Knoxville (UTK); Peterson, Gregory D. [University of Tennessee, Knoxville (UTK)

2012-01-01

As cyber attacks become increasingly sophisticated, the security measures used to mitigate the risks must also increase in sophistication. One time password (OTP) systems provide strong authentication because security credentials are not reusable, thus thwarting credential replay attacks. The credential changes regularly, making brute-force attacks significantly more difficult. In high performance computing, end users may require access to resources housed at several different service provider locations. The ability to share a strong token between multiple computing resources reduces cost and complexity. The National Science Foundation (NSF) Extreme Science and Engineering Discovery Environment (XSEDE) provides access to digital resources, including supercomputers, data resources, and software tools. XSEDE will offer centralized strong authentication for services amongst service providers that leverage their own user databases and security profiles. This work implements a scalable framework built on standards to provide federated secure access to distributed cyberinfrastructure.

Federal laboratories for the 21st century

Energy Technology Data Exchange (ETDEWEB)

Gover, J. [Sandia National Labs., Albuquerque, NM (United States); Huray, P.G. [Univ. of South Carolina, Columbia, SC (United States)

1998-04-01

Federal laboratories have successfully filled many roles for the public; however, as the 21st Century nears it is time to rethink and reevaluate how Federal laboratories can better support the public and identify new roles for this class of publicly-owned institutions. The productivity of the Federal laboratory system can be increased by making use of public outcome metrics, by benchmarking laboratories, by deploying innovative new governance models, by partnerships of Federal laboratories with universities and companies, and by accelerating the transition of federal laboratories and the agencies that own them into learning organizations. The authors must learn how government-owned laboratories in other countries serve their public. Taiwan`s government laboratory, Industrial Technology Research Institute, has been particularly successful in promoting economic growth. It is time to stop operating Federal laboratories as monopoly institutions; therefore, competition between Federal laboratories must be promoted. Additionally, Federal laboratories capable of addressing emerging 21st century public problems must be identified and given the challenge of serving the public in innovative new ways. Increased investment in case studies of particular programs at Federal laboratories and research on the public utility of a system of Federal laboratories could lead to increased productivity of laboratories. Elimination of risk-averse Federal laboratory and agency bureaucracies would also have dramatic impact on the productivity of the Federal laboratory system. Appropriately used, the US Federal laboratory system offers the US an innovative advantage over other nations.

An Improved Strong Tracking Cubature Kalman Filter for GPS/INS Integrated Navigation Systems.

Science.gov (United States)

Feng, Kaiqiang; Li, Jie; Zhang, Xi; Zhang, Xiaoming; Shen, Chong; Cao, Huiliang; Yang, Yanyu; Liu, Jun

2018-06-12

The cubature Kalman filter (CKF) is widely used in the application of GPS/INS integrated navigation systems. However, its performance may decline in accuracy and even diverge in the presence of process uncertainties. To solve the problem, a new algorithm named improved strong tracking seventh-degree spherical simplex-radial cubature Kalman filter (IST-7thSSRCKF) is proposed in this paper. In the proposed algorithm, the effect of process uncertainty is mitigated by using the improved strong tracking Kalman filter technique, in which the hypothesis testing method is adopted to identify the process uncertainty and the prior state estimate covariance in the CKF is further modified online according to the change in vehicle dynamics. In addition, a new seventh-degree spherical simplex-radial rule is employed to further improve the estimation accuracy of the strong tracking cubature Kalman filter. In this way, the proposed comprehensive algorithm integrates the advantage of 7thSSRCKF’s high accuracy and strong tracking filter’s strong robustness against process uncertainties. The GPS/INS integrated navigation problem with significant dynamic model errors is utilized to validate the performance of proposed IST-7thSSRCKF. Results demonstrate that the improved strong tracking cubature Kalman filter can achieve higher accuracy than the existing CKF and ST-CKF, and is more robust for the GPS/INS integrated navigation system.

"Our federalism" moves indoors.

Science.gov (United States)

Ruger, Theodore W

2013-04-01

A great deal of the US Supreme Court's federalism jurisprudence over the past two decades has focused on the outer limits of federal power, suggesting a mutually exclusive division of jurisdiction between the states and the federal government, where subjects are regulated by one sovereign or the other but not both. This is not an accurate picture of American governance as it has operated over the past half century - most important areas of American life are regulated concurrently by both the federal government and the states. The Supreme Court's June 2012 decision clearing the way for the Patient Protection and Affordable Care Act (PPACA) to move forward thus should not be regarded as an affront to state sovereignty but as a realistic embrace of state power in its active, modern form. The PPACA is infused with multiple major roles for the states, and as the statute goes into operation over the next few years, states retain, and are already exercising, substantial policy discretion.

Family presence preference when patients are receiving resuscitation in an accident and emergency department.

Science.gov (United States)

Hung, Maria S Y; Pang, Samantha M C

2011-01-01

This paper is a report of a study to illuminate the experience of family members whose relatives survived the resuscitation in an accident and emergency department, and their preferences with regard to being present. Family presence during resuscitation can offer benefits to both patient and family members, and large healthcare organizations support and recommend offering the option for their presence. However, many staff believe that this is too distressing or traumatic for families and that they would interfere with the resuscitation process. An interpretive phenomenological approach was used to collect data in 2007-2008 with 18 family members of patients who survived life-sustaining interventions in an accident and emergency department in Hong Kong. Audio-recorded interviews were transcribed verbatim for thematic analysis and verified with the participants in second interviews. None of the family members was present in resuscitation room during the life-sustaining interventions, and five entered the room after the patients' condition was stable. The majority indicated a strong preference to be present if given the option. Three interrelated themes emerged: (i) emotional connectedness, (ii) knowing the patient, and (iii) perceived (in)appropriateness, with 10 subthemes representing affective, rational and contextual determinants of family presence preferences. The interplay of these determinants and how they contributed to strong or weak preference for family presence was analysed. Variations among the contributing determinants to each family member's preference to be present were revealed. Appropriate nursing interventions, policy and guidelines should be developed to meet individualized needs during such critical and life-threatening moments in accident and emergency departments. © 2010 Blackwell Publishing Ltd.

Girls, until a boy says the opposite: language and presence

OpenAIRE

Izquierdo, Catalina; Rosano, Santiago

2017-01-01

This work is a reflection on the relationship between the use of language and presence. The guidelines given by the Royal Spanish Academy, which advocatesthe use of male generically, are questioned. It seems that being a girl is possible  as long as there is not a boy present, at that time her feminine identity is invisible. The rules of the Royal Academy, made from a vision of purely linguistic language, are refuted by several authors who argue that the language has a strong ideological char...

Drag force in strongly coupled, anisotropic plasma at finite chemical potential

Energy Technology Data Exchange (ETDEWEB)

Chakraborty, Somdeb; Haque, Najmul [Theory Division, Saha Institute of Nuclear Physics,1/AF Bidhannagar, Kolkata-700 064 (India)

We employ methods of gauge/string duality to analyze the drag force on a heavy quark moving through a strongly coupled, anisotropic N=4,SU(N) super Yang-Mills plasma in the presence of a finite U(1) chemical potential. We present numerical results valid for any value of the anisotropy parameter and the U(1) charge density and arbitrary direction of the quark velocity with respect to the direction of anisotropy. In the small anisotropy limit we are also able to furnish analytical results.

Detectable gravitational waves from very strong phase transitions in the general NMSSM

International Nuclear Information System (INIS)

Huber, Stephan J.; Nardini, Germano; Bern Univ.

2015-12-01

We study the general NMSSM with an emphasis on the parameter regions with a very strong first-order electroweak phase transition (EWPT). In the presence of heavy fields coupled to the Higgs sector, the analysis can be problematic due to the existence of sizable radiative corrections. In this paper we propose a subtraction scheme that helps to circumvent this problem. For simplicity we focus on a parameter region that is by construction hidden from the current collider searches. The analysis proves that (at least) in the identified parameter region the EWPT can be very strong and striking gravitational wave signals can be produced. The corresponding gravitational stochastic background can potentially be detected at the planned space-based gravitational wave observatory eLISA, depending on the specific experiment design that will be approved.

Promoting cooperative federalism through state shared savings.

Science.gov (United States)

Weil, Alan

2013-08-01

The Affordable Care Act is transforming American federalism and creating strain between the states and the federal government. By expanding the scale of intergovernmental health programs, creating new state requirements, and setting the stage for increased federal fiscal oversight, the act has disturbed an uneasy truce in American federalism. This article outlines a policy proposal designed to harness cooperative federalism, based on the shared state and federal desire to control health care cost growth. The proposal, which borrows features of the Medicare Shared Savings Program, would provide states with an incentive in the form of an increased share of the savings they generate in programs that have federal financial participation, as long as they meet defined performance standards.

SU-E-T-227: Could the Alpha/Beta Ratio Change in a Strong Magnetic Field?

Energy Technology Data Exchange (ETDEWEB)

Pang, G [Odette Cancer Centre, 2075 Bayview Avenue, Toronto M4N 3M5, Canada and Sunnybrook Research Institute and Departments of Radiation Oncology and Medical Biophysics, University of Toronto, Toronto (Canada)

2015-06-15

Purpose: Magnetic resonance imaging (MRI) is being integrated into radiotherapy delivery for MRI-guided radiotherapy. The presence of a strong magnetic field from a MRI machine during radiotherapy delivery presents a new challenge since the trajectories of electrons liberated by ionizing radiation in patients are strongly dependent on the applied magnetic field. The purpose of this work is to explore the potential effect of a strong magnetic field on the α/β ratio, an important radiobiological parameter in radiotherapy. Methods: Based on the theory of dual radiation action, the α/β ratio can be expressed by an integral of the product of two microdosimetry quantities γ(x) and t(x), where γ(x) is the probability that two energy transfers, a distance x apart, results in a lesion, and t(x) is the proximity function, which is the energy-weighted point-pair distribution of distances between energy transfer points in a track. The quantity t(x) depends on the applied magnetic field. An analytical approach has been used to derive a formula that can be used to calculate the α/β ratio in an extremely strong magnetic field. Results: The α/β ratio has been evaluated in the special case when the applied magnetic field approaches infinity, which gives the upper limit of the potential change of the α/β ratio due to the presence of a strong magnetic field. For V79 Chinese hamster cells it has been shown that the α/β ratio could be increased by 2.90 times for Pd-103, 2.97 times for I-125 and about 2.3 times for Co-60 sources when the applied magnetic field approaches infinity. Conclusion: It has been shown theoretically that the α/β ratio can change in a strong magnetic field, and there could be up to a nearly three-fold increase in the α/β ratio, depending on the strength of the applied magnetic field, the cell type and the radiation used.

2006-10-01

Full Text Available Abstract Background Patients with diabetes already fulfill one diagnostic criterion for MS according to the existing classifications. Our aim was to identify one single clinical parameter, which could effectively predict the presence of MS in patients with type 2 diabetes. Methods We studied all patients with type 2 diabetes who attended our Diabetes Outpatient Clinic during a three-month period. Waist circumference, blood pressure and serum lipids were measured. Establishment of MS diagnosis was based a on National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III criteria and b on International Diabetes Federation (IDF criteria. Receiver operating characteristic (ROC analysis was applied in order to identify the clinical parameter with the highest predictive capability for MS. Among the 500 participating patients (231 males, 269 females, MS was diagnosed in 364 patients (72.8% according to the NCEP ATP III criteria and in 408 patients (81.6% according to the IDF criteria. Results For the NCEP ATP III classification, serum triglycerides (in the overall population, waist and HDL (in female population demonstrated the highest predictive capability for MS (AUCs:0.786, 0.805 and 0.801, respectively. For the IDF classification, no single parameter reached an AUC > 0.800 in the overall population. In females, HDL displayed a satisfactory predictive capability for MS with an AUC which was significantly higher than the one in males (0.785 vs. 0.676, respectively, p Conclusion Elevated serum triglycerides strongly indicate the presence of MS in patients with type 2 diabetes. In female patients with type 2 diabetes, central obesity was the second stronger predictor of MS besides hypertriglyceridemia.

Environmental predictors of ice seal presence in the Bering Sea.

Ice seals overwintering in the Bering Sea are challenged with foraging, finding mates, and maintaining breathing holes in a dark and ice covered environment. Due to the difficulty of studying these species in their natural environment, very little is known about how the seals navigate under ice. Here we identify specific environmental parameters, including components of the ambient background sound, that are predictive of ice seal presence in the Bering Sea. Multi-year mooring deployments provided synoptic time series of acoustic and oceanographic parameters from which environmental parameters predictive of species presence were identified through a series of mixed models. Ice cover and 10 kHz sound level were significant predictors of seal presence, with 40 kHz sound and prey presence (combined with ice cover) as potential predictors as well. Ice seal presence showed a strong positive correlation with ice cover and a negative association with 10 kHz environmental sound. On average, there was a 20-30 dB difference between sound levels during solid ice conditions compared to open water or melting conditions, providing a salient acoustic gradient between open water and solid ice conditions by which ice seals could orient. By constantly assessing the acoustic environment associated with the seasonal ice movement in the Bering Sea, it is possible that ice seals could utilize aspects of the soundscape to gauge their safe distance to open water or the ice edge by orienting in the direction of higher sound levels indicative of open water, especially in the frequency range above 1 kHz. In rapidly changing Arctic and sub-Arctic environments, the seasonal ice conditions and soundscapes are likely to change which may impact the ability of animals using ice presence and cues to successfully function during the winter breeding season.

Wolf presence and increased willow consumption by Yellowstone elk: implications for trophic cascades.

Science.gov (United States)

Creel, Scott; Christianson, David

2009-09-01

Recent increases in the height and growth ring width of willow (Salix spp.) and other woody plants in the Greater Yellowstone Ecosystem (GYE) have been attributed to a behaviorally mediated trophic cascade from wolves (Canis lupus) to elk (Cervus elaphus) to willows. This hypothesis predicts that individual elk consume less willow in response to the presence of wolves, but this prediction has not been directly tested with data from elk. We collected 727 fecal samples from elk in the Gallatin Canyon portion of the GYE over three winters and used microhistological methods to quantify the proportion of willow in each sample. We then tested the effect of wolf presence on willow consumption by elk, controlling for the effects of snow conditions, sex, and habitat type. During the period of study, 8-17 wolves occupied the study area, and wolves were locally present on 49% of 260 sampling days, stratified at two-week intervals across three drainages. Over the three years combined, willow consumption was related to snow conditions, wolf presence, and a wolf X sex interaction. As expected, willow consumption increased with deeper and less penetrable snow, and this effect was strong. Contrary to expectation, willow consumption increased in the presence of wolves. As with other aspects of antipredator behavior, wolves had different effects on willow consumption by males and females. Finally, we aggregated the data to estimate winter-long mean willow consumption within each drainage; at this broader scale, willow consumption again increased as predation risk increased. In summary, willow consumption was more strongly affected by snow conditions than by the presence of wolves. Interactions between elk and willow were affected by wolves, but not as predicted by the hypothesis that wolf presence favors willow release through a reduction in the selection of willow by individual elk. If a trophic cascade is operating, our results suggest that a decline in the size of the elk

FEATURES OF PERFECT AND IMPERFECT RESERVES AND RESERVE FUNDS WITHIN THE FEDERAL BUDGET OF THE RUSSIAN FEDERATION

Full Text Available During the past two years (2016–2017, the mass media was engaged in tense discussion about the status and flow of funds within the two reserves – the Reserve Fund of the Russian Federation and the National Welfare Fund. The Reserve Fund of the Russian Federation aroused especial worries among the experts. Its funds rapidly declined and by December 2017 they were fully used to cover the deficit of the domestic budget. In accordance with the law “On Amendments to the Budget Code of the Russian Federation in the Use of Oil and Gas Revenues of the Federal Budget,” from February 1, 2018, the Reserve Fund of the Russian Federation will cease to exist. For financial theory, this fact can serve as an illustration of the process of forming the foundations of budgetary financial security, their change over time, circumstances and options the government can take to modify them. At the same time, there are other types of financial resources within the federal budget. Their diversity necessitates their classification in order to identify groups and types with similar characteristics. However, in financial theory, many types of reserves are not described in detail, and some are not described at all. This article introduces the concepts of “perfect” and “imperfect” reserves, for their characterization as part of the federal budget. The Russian Reserve Fund and the National Welfare Fund (Sovereign Funds are the examples of perfect financial reserves. Imperfect reserves comprise a large group of reserve funds that are included in the federal budget, for example, the Reserve Fund of the President of the Russian Federation and the Reserve Fund of the Government of the Russian Federation, the Reserve Fund of the Government of the Russian Federation for the prevention and control of emergencies and impact of natural disasters. The introduction of new typological features largely clarifies the situation with increased attention to one type of reserves

2005-01-01

One year ago, Federal Minister for the Environment Juergen Trittin expressed doubt about the long-term viability of the federal states' acting on behalf of the federal government in the field of atomic energy law administration. An alternative to this type of administration was mentioned, namely direct execution by the feral government, and a thorough examination was announced. This was to show which type of administration would achieve maximum safety for the residual operating lives of nuclear power plants. Kienbaum Management Consultants were commissioned to evaluate the current status and potential alternative structures. That study was performed within the framework of one of the key projects in reactor safety of the Federal Ministry for the Environment, Nature Conservation, and Nuclear Safety (BMU), namely the reform of nuclear administration. Further steps to be taken by the BMU by the end of this parliamentary term are presented. The federal state are to be approached in an attempt to conduct an unbiased discussion of the pros and cons of the alternatives to administration by the federal states on behalf of the federal government. Questions will be clarified which need to be examined in depth before direct administration by the federal government can be introduced. These include constitutional matters and matters of costing in financing the higher-level federal authority as well as specific questions about the organization of that authority. The purpose is to elaborate, by the end of this parliamentary term, a workable concept of introducing direct federal administration of nuclear safety. (orig.)

The calculation decides the integrity of the safety latch that will hold the strong-back to the pump during lifting. The safety latch will be welded to the strong-back and will latch to a 1.5-in. dia cantilever rod welded to the pump baseplate. The static and dynamic analysis shows that the safety latch will hold the strong-back to the pump if the friction clamps fail and the pump become free from the strong-back. Thus, the safety latch will meet the requirements of the Lifting and Rigging Manual for under the hook lifting for static loading; it can withstand shock loads from the strong-back falling 0.25 inch

Lanahan, Lauren; Graddy-Reed, Alexandra; Feldman, Maryann P

2016-01-01

The extent to which federal investment in research crowds out or decreases incentives for investment from other funding sources remains an open question. Scholarship on research funding has focused on the relationship between federal and industry or, more comprehensively, non-federal funding without disentangling the other sources of research support that include nonprofit organizations and state and local governments. This paper extends our understanding of academic research support by considering the relationships between federal and non-federal funding sources provided by the National Science Foundation Higher Education Research and Development Survey. We examine whether federal research investment serves as a complement or substitute for state and local government, nonprofit, and industry research investment using the population of research-active academic science fields at U.S. doctoral granting institutions. We use a system of two equations that instruments with prior levels of both federal and non-federal funding sources and accounts for time-invariant academic institution-field effects through first differencing. We estimate that a 1% increase in federal research funding is associated with a 0.411% increase in nonprofit research funding, a 0.217% increase in state and local research funding, and a 0.468% increase in industry research funding, respectively. Results indicate that federal funding plays a fundamental role in inducing complementary investments from other funding sources, with impacts varying across academic division, research capacity, and institutional control.

Program status of the high temperature reactor development in the Federal Republic of Germany

International Nuclear Information System (INIS)

1984-01-01

The status of the HTR development program in the Federal Republic of Germany in 1984 is characterized by the beginning of a transition phase from a national program to a commercial program. In the last 20 years the HTR technology program was strongly, nearly completely supported by the Federal Government and the State Government of North-Rhine-Westfalia. Funding of the program up to now exceeded 5 billion DM. Within this framework it was possible to establish competent-reactor-system companies, to enable industries to supply HTR- specific components including fuel elements and nuclear graphites, to maintain the strong engagement of the national centre KFA Juelich in general R and D activities, to build and operate the AVR-plant for more than 16 years, to erect the demonstration plant THTR-300 now approaching completion and to build and operate many efficient test facilities. Thereby the HTR technology development achieved a stage of maturity which is not only considered to be most advanced, but is also ready now for commerical deployment. The assessment report which comprised both the fast breeder and the HTR development included all major impacts, such as history, status, prospects, benefits, industrial aspects and international developments of the technology. The program description is facilitated by distinguishing the five major program elements: AVR, THTR-300, THTR follow-up plant, nuclear process heat program, fuel cycle activities

Stability of a Bose Condensate in the presence of regular and irregular potentials

International Nuclear Information System (INIS)

Gunn, J.M.F.

1984-05-01

The stability of an interacting Bose Condensate in the presence of a periodic potential is discussed. The condensate is destroyed if the potential is sufficiently strong, for certain densities of particles. Secondly irregular potentials of two types are considered: a dilute set of ''defect'' potentials in an otherwise periodic potential; and a highly irregular potential. In the first case, if the defect potential is sufficiently strong, the condensate is found to have a depletion which varies with the concentration of the defects. In the latter case it is argued that the condensate is totally destroyed. The consequences of the theory for experiments on 4 He films are discussed, and some new experiments proposed. (author)

Spin effects in strong-field laser-electron interactions

The electron spin degree of freedom can play a significant role in relativistic scattering processes involving intense laser fields. In this contribution we discuss the influence of the electron spin on (i) Kapitza-Dirac scattering in an x-ray laser field of high intensity, (ii) photo-induced electron-positron pair production in a strong laser wave and (iii) multiphoton electron-positron pair production on an atomic nucleus. We show that in all cases under consideration the electron spin can have a characteristic impact on the process properties and their total probabilities. To this end, spin-resolved calculations based on the Dirac equation in the presence of an intense laser field are performed. The predictions from Dirac theory are also compared with the corresponding results from the Klein-Gordon equation.

Negative mobility of a Brownian particle: Strong damping regime

Science.gov (United States)

Słapik, A.; Łuczka, J.; Spiechowicz, J.

2018-02-01

We study impact of inertia on directed transport of a Brownian particle under non-equilibrium conditions: the particle moves in a one-dimensional periodic and symmetric potential, is driven by both an unbiased time-periodic force and a constant force, and is coupled to a thermostat of temperature T. Within selected parameter regimes this system exhibits negative mobility, which means that the particle moves in the direction opposite to the direction of the constant force. It is known that in such a setup the inertial term is essential for the emergence of negative mobility and it cannot be detected in the limiting case of overdamped dynamics. We analyse inertial effects and show that negative mobility can be observed even in the strong damping regime. We determine the optimal dimensionless mass for the presence of negative mobility and reveal three mechanisms standing behind this anomaly: deterministic chaotic, thermal noise induced and deterministic non-chaotic. The last origin has never been reported. It may provide guidance to the possibility of observation of negative mobility for strongly damped dynamics which is of fundamental importance from the point of view of biological systems, all of which in situ operate in fluctuating environments.

Mismeasurement and the resonance of strong confounders: correlated errors.

Science.gov (United States)

Marshall, J R; Hastrup, J L; Ross, J S

1999-07-01

Confounding in epidemiology, and the limits of standard methods of control for an imperfectly measured confounder, have been understood for some time. However, most treatments of this problem are based on the assumption that errors of measurement in confounding and confounded variables are independent. This paper considers the situation in which a strong risk factor (confounder) and an inconsequential but suspected risk factor (confounded) are each measured with errors that are correlated; the situation appears especially likely to occur in the field of nutritional epidemiology. Error correlation appears to add little to measurement error as a source of bias in estimating the impact of a strong risk factor: it can add to, diminish, or reverse the bias induced by measurement error in estimating the impact of the inconsequential risk factor. Correlation of measurement errors can add to the difficulty involved in evaluating structures in which confounding and measurement error are present. In its presence, observed correlations among risk factors can be greater than, less than, or even opposite to the true correlations. Interpretation of multivariate epidemiologic structures in which confounding is likely requires evaluation of measurement error structures, including correlations among measurement errors.

In the Russian Federation (RF), management of radioactive wastes will be carried out within the framework of the Federal Target Program for management of radioactive wastes and used nuclear materials for the period 1996-2005. The agency within the RF responsible for this program is the Ministry of Russian Federation on Atomic Energy. Current radioactive waste disposal activities are focused on creating regional repositories for wastes generated by radiochemical production, nuclear reactors, science centers, and from other sources outside of the nuclear-fuel cycle (the latter wastes are managed by Scientific and Industrial Association, 'RADON'). Wastes of these types are in temporary storage, with the exception of non-fuel cycle wastes which are in long term storage managed by SAI 'RADON'. The criteria for segregating between underground or near-surface disposal of radioactive waste are based on the radiation fields and radionuclide composition of the wastes. The most progress in creating regional repositories has been made in the Northwest region of Russia. However, development of a detailed design has begun for a test facility in the Northeast for disposal of radioactive wastes generated in Murmansk and Arkhangelsk provinces. The feasibility study for construction of this facility is being evaluated by state monitoring organizations, the heads of administrations of the Arkhangelsk and Murmansk provinces, and Minatom of Russia

Geographic information systems (GIS) technology was applied to analyze federal energy demand across the contiguous US. Several federal energy clusters were previously identified, including Hampton Roads, Virginia, which was subsequently studied in detail. This study provides an analysis of three additional diverse federal energy clusters. The analysis shows that there are potential sites in various federal energy clusters that could be evaluated further for placement of an integral pressurized-water reactor (iPWR) to support meeting federal clean energy goals.

Evaluating Presence Data versus Expert Opinions to Assess Occurrence, Habitat Preferences and Landscape Permeability: A Case Study of Butterflies

Full Text Available We explored how presence data and expert opinions performed with respect to identifying the ecological preferences and the spatial needs of six butterfly species in the Federal State of Saxony, Germany. We used presence records and a land-cover map. In parallel we used expert responses to evaluate the 40 land-cover types occurring in the map, in terms of both suitability and permeability for the six species. Presence data were translated into preferences through Ivlev’s electivity indices (IEI. Visual analysis of preference maps based on IEI showed a distinct pattern of suitable versus less suitable areas. Similarly, spatial analyses found that presence-points were closer to suitability areas based on IEI than those that were based on expert data. However, in case of mismatches between expert and presence-based evaluations, independent experts identified the expert evaluation as better and considered IEI outcomes as wrong. We found a medium to high correlation between land-cover class suitability and permeability based on expert opinions for all species. This indicates that expert evaluation of permeability is affiliated with habitat suitability. Integration of species-presence data and expert-knowledge about species could enhance our capabilities to understand and potentially map suitability while gathering information about suitability and permeability separately can improve species conservation planning.

Accident statistics on all modes of transportation are available as risk assessment analytical tools through several federal agencies. This paper reports on the examination of the accident databases by personal contact with the federal staff responsible for administration of the database programs. This activity, sponsored by the Department of Energy through Sandia National Laboratories, is an overview of the national accident data on highway, rail, air, and marine shipping. For each mode, the definition or reporting requirements of an accident are determined and the method of entering the accident data into the database is established. Availability of the database to others, ease of access, costs, and who to contact were prime questions to each of the database program managers. Additionally, how the agency uses the accident data was of major interest

Esophageal motor disorder (EMD) has been shown to be associated with gastroesophageal reflux disease (GERD). However, the association of EMD with a Barrett's esophagus (BE) is controversial. Our objective was to evaluate whether the presence of EMD was an independent factor associated with BE. A retrospective case-control study was conducted in GERD patients who all had oeso-gastroduodenal endoscopy and high-resolution esophageal manometry. The clinical data collected was known or potential risk factors for BE: male gender, smoking and alcohol consumption, age, body mass index, presence of hiatal hernia, frequency, and age of GERD. EMD were classified according to the Chicago classification into: ineffective motor syndrome, fragmented peristalsis and absence of peristalsis, lower esophageal sphincter hypotonia. Two hundred and one patients (101 in the GERD + BE group and 100 in the GERD without BE) were included. In univariate analysis, male gender, alcohol consumption, presence of hiatal hernia, and EMD appeared to be associated with the presence of BE. In a multivariate analysis, 3 independent factors were identified: the presence of EMD (odds ratio [OR], 3.99; 95% confidence interval [CI], 1.71-9.28; P = 0.001), the presence of hiatal hernia (OR, 5.60; 95% CI, 2.45-12.76; P ＜ 0.001), Helicobacter pylori infection (OR, 0.08; 95% CI, 0.01-0.84; P = 0.035). The presence of EMD (particularly ineffective motor syndrome and lower esophageal sphincter hypotonia) is a strong independent associated factor of BE. Searching systematically for an EMD in patients suffering from GERD could be a new strategy to organize the endoscopic follow-up.

The Russian Federation health system has its roots in the country's complex political history. The Ministry of Health and Social Development and its associated federal services are the principal Russian institutions subserving the Russian Federation. Funding for the health system goes through 2 channels: the general revenue budget managed by federal, regional, and local health authorities, and the Mandatory Health Insurance Fund. Although the Soviet Union was the first country in the world to guarantee free medical care as a constitutional right to all its citizens, quality and accessibility are in question.

Characteristics of strongly-forced turbulent jets and non-premixed jet flames

Previous researchers have demonstrated that strong pulsations of the fuel flow rate can significantly reduce the flame length and luminosity of laminar/transitional non-premixed jet flames. The physical mechanisms responsible for these changes are investigated experimentally in acoustically-forced jet flows where the peak velocity fluctuations are up to eight times the mean flow velocity. Both reacting and non-reacting flows were studied and Reynolds numbers, based on the mean flow properties, ranged from 800 to 10,000 (corresponding to peak Reynolds numbers of 1,450-23,000), and forcing frequencies ranged from 290 to 1,140 Hz. Both the first and second organ-pipe resonance modes of the fuel delivery tube were excited to obtain these frequencies. An analysis of the acoustic forcing characteristics within the resonance tube is provided in order to understand the source of the high amplitude forcing. Flow visualization of jets with first resonant forcing confirms the presence of large-scale coherent vortices and strong reverse flow near the exit of the fuel tube. With second-resonant forcing, however, vortices are not emitted from the tube as they are drawn back into the fuel tube before they can fully form. Increased fine-scale turbulence is associated with both resonant cases, but particularly at second resonance. The power spectra of the velocity fluctuations for a resonantly pulsed jet show the presence of an inertial subrange indicating that the flow becomes fully turbulent even for mean-Reynolds-number jets that are nominally laminar. It is shown that these pulsed jet flows exhibit strong similarities to synthetic jets and that the Strouhal number, based on the maximum velocity at the fuel tube exit, is the dominant parameter for scaling these flows. The Strouhal number determines the downstream location where the coherent vortices breakdown, and is found to provide better collapse of flame length data (both current and previous) than other parameters that have

Persistent current of relativistic electrons on a Dirac ring in presence of impurities

KAUST Repository

Ghosh, Sumit; Saha, Arijit

2014-01-01

We study the behaviour of persistent current of relativistic electrons on a one dimensional ring in presence of attractive/repulsive scattering potentials. In particular, we investigate the persistent current in accordance with the strength as well as the number of the scattering potential. We find that in presence of single scatterer the persistent current becomes smaller in magnitude than the scattering free scenario. This behaviour is similar to the non-relativistic case. Even for a very strong scattering potential, finite amount of persistent current remains for a relativistic ring. In presence of multiple scatterer we observe that the persistent current is maximum when the scatterers are placed uniformly compared to the current averaged over random configurations. However if we increase the number of scatterers, we find that the random averaged current increases with the number of scatterers. The latter behaviour is in contrast to the non-relativistic case. © 2014 EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg.

Full Text Available This article provides a geographic and socio-economic description of Krasnodar Krai, one of the federal subjects of the complexly organized Russian Federation. Its size and population are comparable to the ones of smaller European countries, such as Austria, Czech Republic, Republic of Ireland or Denmark, Finland and Slovakia. In comparison to Serbia, this region is somewhat smaller and less densely populated. Its landscape and climate diversity, as well as an abundance of natural resources make a good starting point for a further economic and social development of the region. The agro-industrial complex and tourism are especially developed in this region and are considered its strong points both within Russia and outside its borders. The level of industrial cooperation between Serbia and Russia is considerably lower than in the times of SFRY and USSR. However, it will certainly increase in the future, leading to an intensification of cooperation with Krasnodar region which will not only be based on trade relations.

The Federal Government's authority to give instructions in matters of public administration pursuant to Art. 85 III GG has been gaining in significance over the last few years in the course of federal disputes about the licenses issued to the NUKEM company under atomic energy law, or about the licensing of the Kalkar fast breeder reactor. Proceeding from the above federal controversy about issues relating to atomic energy law, the author extends his study to the general constitutional level, investigating the provisions of the German constitution relating to the supervisory power and the authority to give instructions on the part of the Federal Government, and the rights and means of the Laender governments to defend their administrative rights.

Sub-federal ecological modernization: A case study of Colorado's new energy economy

Science.gov (United States)

Giannakouros, Stratis

European nations have often employed policies of explicit government intervention as a preferred means of addressing environmental and economic challenges. These policies have ranged from grey industrial policies focused solely on industrial growth, competitiveness and innovation to policies of stronger ecological modernization, which seek to align industrial interests with environmental protection. In recent years these policies have been mobilized to address the threat of climate change and promote environmental innovation. While some US Administrations have similarly recognized the need to address these challenges, the particular historical and political institutional dynamics of the US have meant that explicit government intervention has been eschewed in favor of more indirect strategies when dealing with economic and environmental challenges. This is evident in the rise of sub-federal policies at the level of US states. Supported by federal laboratories and public research, US states have adopted policies that look very much like sub-federal versions of industrial or ecological modernization policy. This thesis uses the Colorado case to highlight the importance of sub-federal institutions in addressing environmental and economic challenges in the US and explore its similarities to, and differences from, European approaches. To achieve this goal it first develops an analytical scheme within which to place policy initiatives on a continuum from grey industrial policy to strong ecological modernization policy by identifying key institutions that are influential in each policy type. This analytical scheme is then applied to the transitional renewable energy policy period from 2004-2012 in the state of Colorado. This period starts with the adoption of a renewable energy portfolio in 2004 and includes the `new energy economy' period from 2007-2010 as well as the years since. Looking at three key turning points this paper interprets the `new energy economy' strategy

To explore the characteristics of and interactions between clinicians, patients and family members during management of the deteriorating adult patient in the emergency department. Previous research into family presence during resuscitation has identified many positive outcomes when families are included. However, over the last three decades the epidemiology of acute clinical deterioration has changed, with a decrease in in-hospital cardiac arrests and an increase in acute clinical deterioration. Despite the decrease in cardiac arrests, research related to family presence continues to focus on care during resuscitation rather than care during acute deterioration. Descriptive exploratory study using nonparticipatory observation. Five clinical deterioration episodes were observed within a 50-bed, urban, Australian emergency department. Field notes were taken using a semistructured tool to allow for thematic analysis. Presence, roles and engagement describe the interactions between clinicians, family members and patients while family are present during a patient's episode of deterioration. Presence was classified as no presence, physical presence and therapeutic presence. Clinicians and family members moved through primary, secondary and tertiary roles during patients' deterioration episode. Engagement was observed to be superficial or deep. There was a complex interplay between presence, roles and engagement with each influencing which form the other could take. Current practices of managing family during episodes of acute deterioration are complex and multifaceted. There is fluid interplay between presence, roles and engagement during a patient's episode of deterioration. This study will contribute to best practice, provide a strong foundation for clinician education and present opportunities for future research. © 2017 John Wiley & Sons Ltd.

Understanding the environmental factors that shape microbial communities is crucial, especially in extreme environments, like Antarctica. Two main forces were reported to influence Antarctic soil microbes: birds and plants. Both birds and plants are currently undergoing relatively large changes in their distribution and abundance due to global warming. However, we need to clearly understand the relationship between plants, birds and soil microorganisms. We therefore collected rhizosphere and bulk soils from six different sampling sites subjected to different levels of bird influence and colonized by Colobanthus quitensis and Deschampsia antarctica in Admiralty Bay, King George Island, Maritime Antarctic. Microarray and qPCR assays targeting 16S rRNA genes of specific taxa were used to assess microbial community structure, composition and abundance and analyzed with a range of soil physico-chemical parameters. The results indicated significant rhizosphere effects in four out of the six sites, including areas with different levels of bird influence. Acidobacteria were significantly more abundant in soils with little bird influence (low nitrogen) and in bulk soil. In contrast, Actinobacteria were significantly more abundant in the rhizosphere of both plant species. At two of the sampling sites under strong bird influence (penguin colonies), Firmicutes were significantly more abundant in D. antarctica rhizosphere but not in C. quitensis rhizosphere. The Firmicutes were also positively and significantly correlated to the nitrogen concentrations in the soil. We conclude that the microbial communities in Antarctic soils are driven both by bird and plants, and that the effect is taxa-specific. PMID:23840411

Environmental federalism and US climate change policy

International Nuclear Information System (INIS)

Jaeger, L.M.

2004-01-01

Environmental disputes involving states over the proper state and federal roles have grown in number and magnitude over the last several years, with many disputes engaging dozens of states. States with competing views are fully engaged in the ongoing debate over climate change, a textbook case for testing the contours of environmental federalism. The issue has all the necessary components: transboundary environmental impacts; competing state economic and environmental interests; state self-interest; disagreement on first principles including what is the proper role of the states; and a somewhat ill-defined federal role. With those qualities, one would expect the federal government to step in and regulate. Instead, the federal government has declined to regulate, inviting a national discourse on whether and how to reduce greenhouse gas (GHG) emissions. As of Spring 2004, twenty-eight states have launched or are planning initiatives, some of which will directly regulate sources of GHG emissions. As these programs take root, pressure will build for a greater federal role. This paper will advance the position that even with this building momentum, the federal government is not likely to emulate state programs that mandate CO 2 emission reductions. In the face of high national cost, uncertain environmental benefits, and a history of federal non-regulatory action, federal regulation at this time appears to be a remote possibility. State efforts to address global climate change add value to the debate, but they do not create the cocoon of consensus the federal government seeks before launching mandatory programs of this magnitude. The more likely scenario is that the federal government will continue on its present course, funding research and development, investing in energy efficient technologies, and supporting voluntary measures. Under this scenario, states and the private sector would continue to function as the 'laboratories' to develop new ideas to improve energy

One of the most interesting kind of neutron stars are the pulsars, which are highly magnetized neutron stars with fields up to 10{sup 14} G at the surface. The strength of magnetic field in the center of a neutron star remains unknown. According to the scalar virial theorem, magnetic field in the core could be as large as 10{sup 18} G. In this work we study the influence of strong magnetic fields on the cooling of neutron stars coming from direct Urca process. Direct Urca process is an extremely efficient mechanism for cooling a neutron star after its formation. The matter is described using a relativistic mean-field model at zero temperature with eight baryons (baryon octet), electrons and muons. We obtain the relative population of each species of particles as function of baryon density for different magnetic fields. We calculate numerically the cooling of neutron stars for a parametrized magnetic field and compare the results for the case without a magnetic field.

Critical point in the QCD phase diagram for extremely strong background magnetic fields

International Nuclear Information System (INIS)

Endrödi, Gergely

2015-01-01

Lattice simulations have demonstrated that a background (electro)magnetic field reduces the chiral/deconfinement transition temperature of quantum chromodynamics for eB<1 GeV 2 . On the level of observables, this reduction manifests itself in an enhancement of the Polyakov loop and in a suppression of the light quark condensates (inverse magnetic catalysis) in the transition region. In this paper, we report on lattice simulations of 1+1+1-flavor QCD at an unprecedentedly high value of the magnetic field eB=3.25 GeV 2 . Based on the behavior of various observables, it is shown that even at this extremely strong field, inverse magnetic catalysis prevails and the transition, albeit becoming sharper, remains an analytic crossover. In addition, we develop an algorithm to directly simulate the asymptotically strong magnetic field limit of QCD. We find strong evidence for a first-order deconfinement phase transition in this limiting theory, implying the presence of a critical point in the QCD phase diagram. Based on the available lattice data, we estimate the location of the critical point.

Bound-state β decay of a neutron in a strong magnetic field

Kouzakov, Konstantin A.; Studenikin, Alexander I.

2005-01-01

The β decay of a neutron into a bound (pe - ) state and an antineutrino in the presence of a strong uniform magnetic field (B > or approx. 10 13 G) is considered. The β decay process is treated within the framework of the standard model of weak interactions. A Bethe-Salpeter formalism is employed for description of the bound (pe - ) system in a strong magnetic field. For the field strengths 10 13 18 G the estimate for the ratio of the bound-state decay rate w b and the usual (continuum-state) decay rate w c is derived. It is found that in such strong magnetic fields w b /w c ∼0.1-0.4. This is in contrast to the field-free case, where w b /w c ≅4.2x10 -6 [J. N. Bahcall, Phys. Rev. 124, 495 (1961); L. L. Nemenov, Sov. J. Nucl. Phys. 15, 582 (1972); X. Song, J. Phys. G: Nucl. Phys. 13, 1023 (1987)]. The dependence of the ratio w b /w c on the magnetic field strength B exhibits a logarithmiclike behavior. The obtained results can be important for applications in astrophysics and cosmology

Strong and Electromagnetic Interactions at SPS Energies

CERN Document Server

Ribicki, Andrzej

2009-01-01

Particle production in peripheral Pb+Pb collisions has been measured at a beam energy of 158 GeV per nucleon, corresponding to psNN 17.3 GeV. The measurements provide full double differential coverage in a wide range of longitudinal and transverse momenta, including the central (“mid-rapidity”) area and extending far into the projectile fragmentation region. The resulting analysis shows the heavy ion reaction as a mixture of different processes. In particular, surprising phenomena, like the presence of large and strongly varying structures in the shape of the double differential cross section d2s /dxFd pT , are induced by the final state electromagnetic interaction between produced particles and the charged spectator system. This effect is largest at low transverse momenta, where it results in a deep valley in the xF -dependence of the produced p+/p− ratio. The basic characteristics of the electromagnetic phenomenon described above agree with the results of a theoretical analysis, performed by means of ...

Net fiscal transfers are commonly seen as a possible means to ensure the wellfunctioning of a currency area. We show that U.S. net fiscal transfers, measured as the difference between gross federal revenues and federal expenditures per state, are enormous. Moreover, we run panel regressions...... a system of fiscal federalism which raises the question whether it should be established in the medium- and long-run. If so, which should be the magnitude of net fiscal transfers? We calculate these transfers hypothetically for 1999-2010, using a relative volume comparable to the one in the USA....

Female mosquitoes of some species are generalists and will blood-feed on a variety of vertebrate hosts, whereas others display marked host preference. Anopheles gambiae and Aedes aegypti have evolved a strong preference for humans, making them dangerously efficient vectors of malaria and Dengue haemorrhagic fever. Specific host odours probably drive this strong preference because other attractive cues, including body heat and exhaled carbon dioxide (CO2), are common to all warm-blooded hosts. Insects sense odours via several chemosensory receptor families, including the odorant receptors (ORs), membrane proteins that form heteromeric odour-gated ion channels comprising a variable ligand-selective subunit and an obligate co-receptor called Orco (ref. 6). Here we use zinc-finger nucleases to generate targeted mutations in the orco gene of A. aegypti to examine the contribution of Orco and the odorant receptor pathway to mosquito host selection and sensitivity to the insect repellent DEET (N,N-diethyl-meta-toluamide). orco mutant olfactory sensory neurons have greatly reduced spontaneous activity and lack odour-evoked responses. Behaviourally, orco mutant mosquitoes have severely reduced attraction to honey, an odour cue related to floral nectar, and do not respond to human scent in the absence of CO2. However, in the presence of CO2, female orco mutant mosquitoes retain strong attraction to both human and animal hosts, but no longer strongly prefer humans. orco mutant females are attracted to human hosts even in the presence of DEET, but are repelled upon contact, indicating that olfactory- and contact-mediated effects of DEET are mechanistically distinct. We conclude that the odorant receptor pathway is crucial for an anthropophilic vector mosquito to discriminate human from non-human hosts and to be effectively repelled by volatile DEET.

Strongly Coupled Chameleons and the Neutronic Quantum Bouncer

International Nuclear Information System (INIS)

Brax, Philippe; Pignol, Guillaume

2011-01-01

We consider the potential detection of chameleons using bouncing ultracold neutrons. We show that the presence of a chameleon field over a planar plate would alter the energy levels of ultracold neutrons in the terrestrial gravitational field. When chameleons are strongly coupled to nuclear matter, β > or approx. 10 8 , we find that the shift in energy levels would be detectable with the forthcoming GRANIT experiment, where a sensitivity of the order of 1% of a peV is expected. We also find that an extremely large coupling β > or approx. 10 11 would lead to new bound states at a distance of order 2 μm, which is already ruled out by previous Grenoble experiments. The resulting bound, β 11 , is already 3 orders of magnitude better than the upper bound, β 14 , from precision tests of atomic spectra.

Let E be a real q-uniformly smooth Banach space. Suppose T is a strongly pseudo-contractive map with open domain D(T) in E. Suppose further that T has a fixed point in D(T). Under various continuity assumptions on T it is proved that each of the Mann iteration process or the Ishikawa iteration method converges strongly to the unique fixed point of T. Related results deal with iterative solutions of nonlinear operator equations involving strongly accretive maps. Explicit error estimates are also provided. (author). 38 refs

CMS Use of a Data Federation

CERN Document Server

Bloom, Kenneth Arthur

2014-01-01

CMS is in the process of deploying an Xrootd based infrastructure to facilitate a global data federation. The services of the federation are available to export data from half the physical capacity and the majority of sites are configured to read data over the federation as a back-up. CMS began with a relatively modest set of use-cases for recovery of failed local file opens, debugging and visualization. CMS is finding that the data federation can be used to support small scale analysis and load balancing. Looking forward we see potential in using the federation to provide more flexibility in the location workflows are executed as the differenced between local access and wide area access are diminished by optimization and improved networking. In this presentation we will discuss the application development work and the facility deployment work, the use-cases currently in production, and the potential for the technology moving forward.

Djouadi, A.; Verzegnassi, C.

1989-12-01

We propose a new and rather unbiased way of determining the value of the strong coupling constant α, if transversally polarized electron-positron beams were available at LEP1. The ratio of azimuthal asymmetries for the production of hadrons to muons in e + e - annihilation is independent of any cut-off procedure and is very sensitive to the value of α s . Moreover we show that on top of Z resonance, it is free from any ambiguity stemming from Standard Model unknown parameters or the possible presence of New Physics

Environmental federalism and US climate change policy

Energy Technology Data Exchange (ETDEWEB)

Jaeger, L.M. [Bracewell and Patterson, LLP (United States)

2004-07-01

Environmental disputes involving states over the proper state and federal roles have grown in number and magnitude over the last several years, with many disputes engaging dozens of states. States with competing views are fully engaged in the ongoing debate over climate change, a textbook case for testing the contours of environmental federalism. The issue has all the necessary components: transboundary environmental impacts; competing state economic and environmental interests; state self-interest; disagreement on first principles including what is the proper role of the states; and a somewhat ill-defined federal role. With those qualities, one would expect the federal government to step in and regulate. Instead, the federal government has declined to regulate, inviting a national discourse on whether and how to reduce greenhouse gas (GHG) emissions. As of Spring 2004, twenty-eight states have launched or are planning initiatives, some of which will directly regulate sources of GHG emissions. As these programs take root, pressure will build for a greater federal role. This paper will advance the position that even with this building momentum, the federal government is not likely to emulate state programs that mandate CO{sub 2} emission reductions. In the face of high national cost, uncertain environmental benefits, and a history of federal non-regulatory action, federal regulation at this time appears to be a remote possibility. State efforts to address global climate change add value to the debate, but they do not create the cocoon of consensus the federal government seeks before launching mandatory programs of this magnitude. The more likely scenario is that the federal government will continue on its present course, funding research and development, investing in energy efficient technologies, and supporting voluntary measures. Under this scenario, states and the private sector would continue to function as the 'laboratories' to develop new ideas to

Electron spin resonance modes in a strong-leg ladder in the Tomonaga-Luttinger liquid phase

Magnetic excitations in the strong-leg quantum spin ladder compound (C7H10N) 2CuBr4 (known as DIMPY) in the field-induced Tomonaga-Luttinger spin-liquid phase are studied by means of high-field electron spin resonance (ESR) spectroscopy. The presence of a gapped ESR mode with unusual nonlinear frequency-field dependence is revealed experimentally. Using a combination of analytic and exact-diagonalization methods, we compute the dynamical structure factor and identify this mode with longitudinal excitations in the antisymmetric channel. We argue that these excitations constitute a fingerprint of the spin dynamics in a strong-leg spin-1/2 Heisenberg antiferromagnetic ladder and owe their ESR observability to the uniform Dzyaloshinskii-Moriya interaction.

The scattering of charged particles in the presence of an homogeneous magnetic field, is studied. Using the Green's function formalism, an appropriate transition amplitude for the scattering process is defined, and an application is done for the scattering by a Coulomb potential in the high energy approximation. For this case, the transition amplitude is obtained in a closed form; its behavior with the magnetic field intensity and initial translational energy is qualitatively discussed. In the ultra-strong field limit, the total transition probability presents periodic resonances with increasing values of the initial translational energy [pt

Enforcement, Integration, and the Future of Immigration Federalism

Directory of Open Access Journals (Sweden)

Cristina Rodriguez

2017-06-01

Full Text Available The federal government has a monopoly over the terms of immigration law, and it superintends the nation’s singular immigration enforcement bureaucracy. But our federalism nonetheless provides a vital playing field for sharp debates over the status of immigrants in American life. The forms of state and local involvement in immigration policy are varied, but they fall into two basic categories of mutually dependent and re-enforcing policies: enforcement federalism and integration federalism. Whereas enforcement federalism concerns the extent to which localities should assist or resist federal removal policies, integration federalism encompasses measures designed to assist immigrants, regardless of status, to plant roots and acculturate to life in the United States. Both forms of immigration federalism take shape through a wide variety of intergovernmental relations, not only between the federal government on the one hand and states and localities on the other, but also between states and the cities within them — an increasingly important dimension of immigration federalism today. These relations have important legal characteristics, and constitutional and statutory law bring them into being and mediate them. But the nature of any given intergovernmental dynamic will be shaped just as much by a combination of ideology and institutional imperatives. These elements can either unite the center and the periphery in common cause or produce the sort of conflict that has made immigration federalism a high-profile issue for decades. Given the density of the intergovernmental dynamics that shape the country’s immigration policy, developing a comprehensive strategy for immigration federalism requires more than a predilection toward or away from centralization of government authority. It requires a clear view on the appropriate metes and bounds of immigration enforcement, as well as a set of beliefs about the proper place in the social order of

Nuclear waste management: a challenge to Federalism

International Nuclear Information System (INIS)

Lucas, P.

1979-01-01

The controversy over state/Federal authority over waste disposal has already had a significant effect regardless of the choice Congress ultimately makes between an informal deference to state will and a statutory authorization of state control over Federal repositories. The highly emotional issue of local disposal of nuclear waste and the assertions of state control over waste disposal have made the nation and the Federal bureaucracy more aware of the status of the waste management program. State resistance to Federal siting efforts and the passage of state waste disposal legislation has compelled the Federal government to provide the states with a larger role in waste management. State power to exclude Federal repositories would give states additional political leverage. Ideally, public attention and effective state veto power will contribute to a more successful program, without impeding progress toward the immediate goal of siting and developing permanent repositories

Federal coal lease readjustments: will reason prevail

Energy Technology Data Exchange (ETDEWEB)

Margolf, C W

1988-01-01

After 1920, when the US Congress passed the Mineral Lands Leasing Act (MLLA), coal owned by the Federal government could only be developed by leasing under the MLLA. Most Federally owned coal is in the west, where the Federal government enjoys a near monopoly in coal ownership and its development. In 1976, congress enacted the Federal Coal Leasing Amendments ACT (FCLAA), over President Ford's veto, in order to: increase rents and royalties on Federal coal leases; force lessees holding Federal coal leases not in production to open mines on the non-producing leases; and end 'speculation' in Federal coal leases. The book maintains that in passing the FCLAA, Congress did not understand the western coal industry, and neither did the Department of the Interior (DOI) in concluding that Congress had mandated that the FCLAA must be applied to pre-FCLAA leases, even those in production, when such leases are readjusted. In the resulting lawsuits, the western coal industry has not been explained to the Federal courts and the decisions regarding the applicability of the FCLAA upon readjustment of pre-FCLAA leases have consequently been wrong. The book examines the record to date and aims to demonstrate the validity of these conclusions. It also describes which actions the DOI should have taken to accomplish the objectives of congress set forth in the FCLAA, to readjust pre-FCLAA leases without litigation.

Abiotic variables accounting for presence of the exotic rainbow trout (Oncorhynchus mykiss in Eastern Quebec Rivers

Directory of Open Access Journals (Sweden)

Thibault I.

2010-10-01

Full Text Available Rainbow trout is an exotic fish species that has been introduced in Quebec (Canada since 1893–1894. Despite spatially-restricted stocking for recreational fishing, the species has spread throughout the Saint Lawrence River. In this study, the relationship between rainbow trout occurrence (presence or absence and abiotic variables (river geomorphology and climate was examined for 91 coastal rivers throughout Eastern Quebec in order to determine which variables promote or impede the ongoing invasion process. Results revealed that rainbow trout presence in Eastern Quebec was primarily determined by geomorphological parameters. The invader’s presence was strongly related to the presence of tributaries (especially larger ones. To a lesser extent, the presence of rainbow trout was positively related to warm spring and summer temperatures and negatively related to the peak flood date occurring during the egg deposition period (May. This study proposes a parsimonious modelling approach to identify which environmental parameters favour the spreading of an invader, even when a limited dataset is available due to the incomplete invasion process.

Complying with the Federal Facilities Compliance Act

International Nuclear Information System (INIS)

Pavetto, C.S.; Watmore, A.S.

1994-01-01

The Federal Facilities Compliance Act (FFCA), signed into law on October 6, 1992, amended the Resource Conservation and Recovery Act (RCRA) to place significant additional environmental compliance responsibilities on federal facilities. The federal government has expressly waived sovereign immunity regarding hazardous waste enforcement action taken against these facilities by the states and the EPA. An exception exists for mixed waste violations. The FFCA defines mixed waste as hazardous waste, as defined by RCRA, combined with source, special nuclear or by-product material that is subject to the Atomic Energy Act of 1954. As the majority owner of mixed waste in the United States, the Department of Energy (DOE) must satisfy several new requirements under the FFCA for their facilities. This paper reviews the FFCA's requirements and how they apply to and may affect the DOE and other federal facilities. Included in the review are responsibilities of federal agencies involved and the role of the EPA and the states. In addition, this paper discusses the intent of the FFCA to encourage development of federal facility agreements (FFA) between federal agencies, the EPA and state environmental regulatory agencies

The most important indicator of a well-managed site cleanup effort may no longer be funding or scientific expertise. While support for federal facility cleanup has included appropriations of more than $10 billion annually, these expenditures alone are unlikely to assure progress toward environmental remediation. open-quotes Trustclose quotes is now overwhelmingly mentioned as a prerequisite for progress with site cleanup in DOE's weapons complex. In part, federal budget deficits are forcing participants to focus on factors that build consensus and lead to cost-effective cleanup actions.

Nucleation of polystyrene latex particles in the presence of gamma-methacryloxypropyltrimethoxysilane: functionalized silica particles.

2006-02-01

Silica/polystyrene nanocomposite particles with different morphologies were synthesized through emulsion polymerization of styrene in the presence of silica particles previously modified by gamma-methacryloxypropyltrimethoxysilane (MPS). Grafting of the silane molecule was performed by direct addition of MPS to the aqueous silica suspension in the presence of an anionic surfactant under basic conditions. The MPS grafting density on the silica surface was determined using the depletion method and plotted against the initial MPS concentration. The influence of the MPS grafting density, the silica particles size and concentration and the nature of the surfactant on the polymerization kinetics and the particles morphology was investigated. When the polymerization was performed in the presence of an anionic surfactant, transmission electron microscopy images showed the formation of polymer spheres around silica for MPS grafting densities lower than typically 1 micromole x m(-2) while the conversion versus time curves indicated a strong acceleration effect under such conditions. In contrast, polymerizations performed in the presence of a larger amount of MPS moieties or in the presence of a non ionic emulsifier resulted in the formation of "excentered" core-shell morphologies and lower polymerization rates. The paper identifies the parameters that allow to control particles morphology and polymerization kinetics and describes the mechanism of formation of the nanocomposite colloids.

Energy exchange in strongly coupled plasmas with electron drift

International Nuclear Information System (INIS)

Akbari-Moghanjoughi, M.; Ghorbanalilu, M.

2015-01-01

In this paper, the generalized viscoelastic collisional quantum hydrodynamic model is employed in order to investigate the linear dielectric response of a quantum plasma in the presence of strong electron-beam plasma interactions. The generalized Chandrasekhar's relativistic degeneracy pressure together with the electron-exchange and Coulomb interaction effects are taken into account in order to extend current research to a wide range of plasma number density relevant to big planetary cores and astrophysical compact objects. The previously calculated shear viscosity and the electron-ion collision frequencies are used for strongly coupled ion fluid. The effect of the electron-beam velocity on complex linear dielectric function is found to be profound. This effect is clearly interpreted in terms of the wave-particle interactions and their energy-exchange according to the sign of the imaginary dielectric function, which is closely related to the wave attenuation coefficient in plasmas. Such kinetic effect is also shown to be in close connection with the stopping power of a charged-particle beam in a quantum plasma. The effect of many independent plasma parameters, such as the ion charge-state, electron beam-velocity, and relativistic degeneracy, is shown to be significant on the growing/damping of plasma instability or energy loss/gain of the electron-beam

Strong interactions and electromagnetism in low-energy hadron physics

International Nuclear Information System (INIS)

Kubis, B.

2002-10-01

In the present work, we study various aspects of the entanglement of the strong and electromagnetic interactions as it is manifest in low-energy hadron physics. In the framework of chiral perturbation theory, two aspects are investigated: the test of the structure of baryons as probed by external electromagnetic currents, and the modification of reactions mediated by the strong interactions in the presence of internal (virtual) photons. In the first part of this work, we study the electromagnetic form factors of nucleons and the ground state baryon octet, as well as strangeness form factors of the nucleon. Emphasis is put on the comparison of a new relativistic scheme for the calculation of loop diagrams to the heavy-baryon formalism, and on the convergence of higher-order corrections in both schemes. The new scheme is shown to yield both a phenomenologically more successful description of the data and better convergence behaviour. In the second part, we study isospin violation in pion-kaon scattering as mediated by virtual photon effects and the light quark mass difference. This investigation is of particular importance for the extraction of scattering lengths from measurements of lifetime and energy levels in pion-kaon atoms. The isospin breaking corrections are shown to be small and sufficiently well under control. (orig.)

One- and two-phonon excitations in strongly deformed triaxial nuclei

International Nuclear Information System (INIS)

Hagemann, G.B.

2003-01-01

The wobbling mode is uniquely related to triaxiality and introduces a series of bands with increasing wobbling phonon number, n ω , and a characteristic large Δ nω =1 E2 strength between the bands. The pattern of γ-transitions between the wobbling excitations will be influenced by the presence of an aligned particle. Evidence for the wobbling mode was obtained recently, and even a two-phonon wobbling excitation has now been identified in 163 Lu. The similarity of the data in 163 Lu to new strongly deformed triaxial bands and connecting transitions in the neighbouring nuclei, 165 Lu and 167 Lu, establishes wobbling as a more general phenomenon in this region.

Virtual Reality (VR) is used for a variety of applications ranging from entertainment to psychological medicine. VR has been demonstrated to influence higher order cognitive functions and cortical plasticity, with implications on phobia and stroke treatment. An integral part for successful VR is a high sense of presence - a feeling of 'being there' in the virtual scenario. The underlying cognitive and perceptive functions causing presence in VR scenarios are however not completely known. It is evident that the brain function is influenced by drugs, such as ethanol, potentially confounding cortical plasticity, also in VR. As ethanol is ubiquitous and forms part of daily life, understanding the effects of ethanol on presence and user experience, the attitudes and emotions about using VR applications, is important. This exploratory study aims at contributing towards an understanding of how low-dose ethanol intake influences presence, user experience and their relationship in a validated VR context. It was found that low-level ethanol consumption did influence presence and user experience, but on a minimal level. In contrast, correlations between presence and user experience were strongly influenced by low-dose ethanol. Ethanol consumption may consequently alter cognitive and perceptive functions related to the connections between presence and user experience.

Stagnation and Storage of Strongly Depleted Melts in Slow-Ultraslow Spreading Oceans: Evidence from the Ligurian Tethys

Science.gov (United States)

Piccardo, Giovanni; Guarnieri, Luisa; Padovano, Matteo

2013-04-01

mantle lithosphere under plagioclase-facies conditions, at shallow lithospheric levels, under brittle conditions and, frequently, after serpentinization. The presence and abundance of strongly depleted melts, which stagnated and were stored in the shallow mantle lithosphere, represent characteristic features of the Ligurian Tethys slow-ultraslow spreading basin. In modern oceans, plagioclase-enriched peridotites are abundant at slow-ultraslow spreading ridges (i.e., Mid-Atlantic Ridge, South-West Indian Ridge and Gakkel Ridge) and were recognized as melt-impregnated peridotites. Moreover, a peculiar gabbro-norite suite was found at MAR DSDP Site 334, indicating the presence of rocks formed by silica-saturated, strongly trace element depleted melts. So far, few studies have been devoted to abyssal plagioclase peridotites despite their relatively high abundance (30% of abyssal peridotites), because of their widespread sea-floor alteration. In some cases, rock freshness allowed us to recognize that the compositions of the plagioclase and clinopyroxene were in equilibrium with the percolated, strongly trace element depleted melts, which were stagnated in the shallow oceanic mantle lithosphere. The presence, abundance and stagnation of silica-saturated, strongly trace element depleted melts in the shallow mantle lithosphere to form plagioclase-enriched peridotites and gabbro-norites, seem to be characteristic and discriminant features of fossil and modern slow-ultraslow spreading basins.

Quantum Stackelberg duopoly in the presence of correlated noise

International Nuclear Information System (INIS)

Khan, Salman; Ramzan, M; Khan, M Khalid

2010-01-01

We study the influence of entanglement and correlated noise using correlated amplitude damping, depolarizing and phase damping channels on the quantum Stackelberg duopoly. Our investigations show that under the influence of an amplitude damping channel a critical point exists for an unentangled initial state at which firms get equal payoffs. The game becomes a follower advantage game when the channel is highly decohered. Two critical points corresponding to two values of the entanglement angle are found in the presence of correlated noise. Within the range of these limits of the entanglement angle, the game is a follower advantage game. In the case of a depolarizing channel, the payoffs of the two firms are strongly influenced by the memory parameter. The presence of quantum memory ensures the existence of the Nash equilibrium for the entire range of decoherence and entanglement parameters for both the channels. A local maximum in the payoffs is observed which vanishes as the channel correlation increases. Moreover, under the influence of the depolarizing channel, the game is always a leader advantage game. Furthermore, it is seen that the phase damping channel does not affect the outcome of the game.

1994-05-31

The Federal Internetworking Requirements Panel (FIRP) was established by the National Institute of Standards and Technology (NIST) to reassess Federal requirements for open systems networks and to recommend policy on the Government`s use of networking standards. The Panel was chartered to recommend actions which the Federal Government can take to address the short and long-term issues of interworking and convergence of networking protocols--particularly the Internet Protocol Suite (IPS) and Open Systems Interconnection (OSI) protocol suite and, when appropriate, proprietary protocols. The Panel was created at the request of the Office of Management and Budget in collaboration with the Federal Networking Council and the Federal Information Resources Management Policy Council. The Panel`s membership and charter are contained in an appendix to this report.

Federation in genomics pipelines: techniques and challenges.

Science.gov (United States)

Chaterji, Somali; Koo, Jinkyu; Li, Ninghui; Meyer, Folker; Grama, Ananth; Bagchi, Saurabh

2017-08-29

Federation is a popular concept in building distributed cyberinfrastructures, whereby computational resources are provided by multiple organizations through a unified portal, decreasing the complexity of moving data back and forth among multiple organizations. Federation has been used in bioinformatics only to a limited extent, namely, federation of datastores, e.g. SBGrid Consortium for structural biology and Gene Expression Omnibus (GEO) for functional genomics. Here, we posit that it is important to federate both computational resources (CPU, GPU, FPGA, etc.) and datastores to support popular bioinformatics portals, with fast-increasing data volumes and increasing processing requirements. A prime example, and one that we discuss here, is in genomics and metagenomics. It is critical that the processing of the data be done without having to transport the data across large network distances. We exemplify our design and development through our experience with metagenomics-RAST (MG-RAST), the most popular metagenomics analysis pipeline. Currently, it is hosted completely at Argonne National Laboratory. However, through a recently started collaborative National Institutes of Health project, we are taking steps toward federating this infrastructure. Being a widely used resource, we have to move toward federation without disrupting 50 K annual users. In this article, we describe the computational tools that will be useful for federating a bioinformatics infrastructure and the open research challenges that we see in federating such infrastructures. It is hoped that our manuscript can serve to spur greater federation of bioinformatics infrastructures by showing the steps involved, and thus, allow them to scale to support larger user bases. © The Author 2017.

Interference effects at photoionization of Rydberg atoms by a strong electromagnetic field

International Nuclear Information System (INIS)

Movsesyan, A.M.; Fedorov, M.V.

1989-01-01

The photoionization of Rydberg atoms in a strong electromagnetic field is considered. Degeneration of the levels with respect to the orbital moment, their Stark splitting and the possibility of resonant interaction with levels of lower energy are taken into account. The complex quasi-energies of the system, photoelectron spectrum in the limit of an infinite duration of interaction and the time dependence of the total ionization probability are found. It is shown that a narrowing of the quasi-energy levels occurs in a strong field. Against a background of the quasi- continuum the quasi-energy spectrum consists of more or less narrow levels. In this case the photoelectron spectrum acquires a multi-peak form. With increasing field strength the height of the peaks increases, whereas their width decreases. The ionization rate decreases with increasing field strength. The presence of a quasi-continuum is the cause of the partially non-exponential nature of the atomic disintegration

High-flux cold rubidium atomic beam for strongly-coupled cavity QED

Energy Technology Data Exchange (ETDEWEB)

Roy, Basudev [Indian Institute of Science Education and Research, Kolkata (India); University of Maryland, MD (United States); Scholten, Michael [University of Maryland, MD (United States)

2012-08-15

This paper presents a setup capable of producing a high-flux continuous beam of cold rubidium atoms for cavity quantum electrodynamics experiments in the region of strong coupling. A 2D{sup +} magneto-optical trap (MOT), loaded with rubidium getters in a dry-film-coated vapor cell, fed a secondary moving-molasses MOT (MM-MOT) at a rate greater than 2 x 10{sup 10} atoms/s. The MM-MOT provided a continuous beam with a tunable velocity. This beam was then directed through the waist of a cavity with a length of 280 μm, resulting in a vacuum Rabi splitting of more than ±10 MHz. The presence of a sufficient number of atoms in the cavity mode also enabled splitting in the polarization perpendicular to the input. The cavity was in the strong coupling region, with an atom-photon dipole coupling coefficient g of 7 MHz, a cavity mode decay rate κ of 3 MHz, and a spontaneous emission decay rate γ of 6 MHz.

Strong-field ionization of xenon dimers: The effect of two-equivalent-center interference and of driving ionic transitions

Science.gov (United States)

Zhang, C.; Feng, T.; Raabe, N.; Rottke, H.

2018-02-01

Strong-field ionization (SFI) of the homonuclear noble gas dimer Xe2 is investigated and compared with SFI of the Xe atom and of the ArXe heteronuclear dimer by using ultrashort Ti:sapphire laser pulses and photoelectron momentum spectroscopy. The large separation of the two nuclei of the dimer allows the study of two-equivalent-center interference effects on the photoelectron momentum distribution. Comparing the experimental results with a new model calculation, which is based on the strong-field approximation, actually reveals the influence of interference. Moreover, the comparison indicates that the presence of closely spaced gerade and ungerade electronic state pairs of the Xe2 + ion at the Xe2 ionization threshold, which are strongly dipole coupled, affects the photoelectron momentum distribution.

Intermittency in Hall-magnetohydrodynamics with a strong guide field

International Nuclear Information System (INIS)

Rodriguez Imazio, P.; Martin, L. N.; Dmitruk, P.; Mininni, P. D.

2013-01-01

We present a detailed study of intermittency in the velocity and magnetic field fluctuations of compressible Hall-magnetohydrodynamic turbulence with an external guide field. To solve the equations numerically, a reduced model valid when a strong guide field is present is used. Different values for the ion skin depth are considered in the simulations. The resulting data are analyzed computing field increments in several directions perpendicular to the guide field, and building structure functions and probability density functions. In the magnetohydrodynamic limit, we recover the usual results with the magnetic field being more intermittent than the velocity field. In the presence of the Hall effect, field fluctuations at scales smaller than the ion skin depth show a substantial decrease in the level of intermittency, with close to monofractal scaling

Novel Ion Trap Design for Strong Ion-Cavity Coupling

Directory of Open Access Journals (Sweden)

Alejandro Márquez Seco

2016-04-01

Full Text Available We present a novel ion trap design which facilitates the integration of an optical fiber cavity into the trap structure. The optical fibers are confined inside hollow electrodes in such a way that tight shielding and free movement of the fibers are simultaneously achievable. The latter enables in situ optimization of the overlap between the trapped ions and the cavity field. Through numerical simulations, we systematically analyze the effects of the electrode geometry on the trapping characteristics such as trap depths, secular frequencies and the optical access angle. Additionally, we simulate the effects of the presence of the fibers and confirm the robustness of the trapping potential. Based on these simulations and other technical considerations, we devise a practical trap configuration that isviable to achieve strong coupling of a single ion.

Esophageal Motor Disorders Are a Strong and Independant Associated Factor of Barrett’s Esophagus

Science.gov (United States)

Bazin, Camille; Benezech, Alban; Alessandrini, Marine; Grimaud, Jean-Charles; Vitton, Veronique

2018-01-01

Background/Aims Esophageal motor disorder (EMD) has been shown to be associated with gastroesophageal reflux disease (GERD). However, the association of EMD with a Barrett’s esophagus (BE) is controversial. Our objective was to evaluate whether the presence of EMD was an independent factor associated with BE. Methods A retrospective case-control study was conducted in GERD patients who all had oeso-gastroduodenal endoscopy and high-resolution esophageal manometry. The clinical data collected was known or potential risk factors for BE: male gender, smoking and alcohol consumption, age, body mass index, presence of hiatal hernia, frequency, and age of GERD. EMD were classified according to the Chicago classification into: ineffective motor syndrome, fragmented peristalsis and absence of peristalsis, lower esophageal sphincter hypotonia. Results Two hundred and one patients (101 in the GERD + BE group and 100 in the GERD without BE) were included. In univariate analysis, male gender, alcohol consumption, presence of hiatal hernia, and EMD appeared to be associated with the presence of BE. In a multivariate analysis, 3 independent factors were identified: the presence of EMD (odds ratio [OR], 3.99; 95% confidence interval [CI], 1.71–9.28; P = 0.001), the presence of hiatal hernia (OR, 5.60; 95% CI, 2.45–12.76; P motor syndrome and lower esophageal sphincter hypotonia) is a strong independent associated factor of BE. Searching systematically for an EMD in patients suffering from GERD could be a new strategy to organize the endoscopic follow-up. PMID:29605977

Strongly coupled chameleon fields: Possible test with a neutron Lloyd's mirror interferometer

Energy Technology Data Exchange (ETDEWEB)

Pokotilovski, Yu.N., E-mail: pokot@nf.jinr.ru [Joint Institute for Nuclear Research, 141980 Dubna, Moscow Region (Russian Federation)

2013-02-26

The consideration of possible neutron Lloyd's mirror interferometer experiment to search for strongly coupled chameleon fields is presented. The chameleon scalar fields were proposed to explain the acceleration of expansion of the Universe. The presence of a chameleon field results in a change of a particle's potential energy in vicinity of a massive body. This interaction causes a phase shift of neutron waves in the interferometer. The sensitivity of the method is estimated.

Nuclear supervision - Administration by the federal states on behalf of the Federal Government or direct federal administration? Evaluation from a practical point of view; Atomaufsicht - Bundesauftragsverwaltung oder Bundeseigenverwaltung? Bewertung aus der Sicht der Praxis

Energy Technology Data Exchange (ETDEWEB)

Cloosters, W. [Ministerium fuer Soziales, Gesundheit und Verbraucherschutz des Landes Schleswig-Holstein, Kiel (Germany). Abt. Reaktorsicherheit

2005-01-01

The organization of supervisory authorities under the Atomic Energy Act is not a new issue. In fact, it was discussed vehemently in the Federal Republic of Germany as far back as in the early fifties. Federal legislation in late 1959 decided to have the Atomic Energy Act executed in part under direct federal responsibility and, as far as the important supervision of the nuclear power plants operated in the Federal Republic of Germany was concerned, by the federal states on behalf of the federal government. Federal Minister for the Environment Trittin reopened the debate about the organization of nuclear administration by announcing his intention to transfer the supervision of nuclear power plants to direct federal administration. This announcement not only raises the question of legal permissibility of transferring nuclear power plant oversight to federal administration, but also requires a critical review, as presented in this article, of practical regulatory supervision to ensure safe operation of nuclear facilities. In this connection, both the actual content of supervisory activities and the way in which they are carried out must be examined in an effort to find an answer based on solid premises to the question raised above. For reasons explained in the contribution, oversight of nuclear power plants cannot be carried out as a centralized function. Instead, the legislative decision of 1959 in favor of the federal states exercising supervision on behalf of the federal government continues to be correct at the present stage also in the light of the steps initiated to opt out of the peaceful uses of nuclear power.

Jeans instability in collisional strongly coupled dusty plasma with radiative condensation and polarization force

International Nuclear Information System (INIS)

Prajapati, R. P.; Bhakta, S.; Chhajlani, R. K.

2016-01-01

The influence of dust-neutral collisions, polarization force, and electron radiative condensation is analysed on the Jeans (gravitational) instability of partially ionized strongly coupled dusty plasma (SCDP) using linear perturbation (normal mode) analysis. The Boltzmann distributed ions, dynamics of inertialess electrons, charged dust and neutral particles are considered. Using the plane wave solutions, a general dispersion relation is derived which is modified due to the presence of dust-neutral collisions, strong coupling effect, polarization force, electron radiative condensation, and Jeans dust/neutral frequencies. In the long wavelength perturbations, the Jeans instability criterion depends upon strong coupling effect, polarization interaction parameter, and thermal loss, but it is independent of dust-neutral collision frequency. The stability of the considered configuration is analysed using the Routh–Hurwitz criterion. The growth rates of Jeans instability are illustrated, and stabilizing influence of viscoelasticity and dust-neutral collision frequency while destabilizing effect of electron radiative condensation, polarization force, and Jeans dust-neutral frequency ratio is observed. This work is applied to understand the gravitational collapse of SCDP with dust-neutral collisions.

[The federal government discourse during the political decentralization process and the obstacles to implement the Brazilian Public Health Care System].

Science.gov (United States)

Pellegrini, Bárbara

2007-01-01

A discourse analysis carried out on basic operating standard Norma Operacional Básica do Sistema Unico de Saúde (NOB-SUS 01/96) of the Brazilian public health care system aiming at locating signs that could allow to identify lines of thought which have influenced health care policies prioritized by the federal administration. The author points out a peculiarity in the kind of discourse employed by the ministry directive: its structure is based on isolated aspects of legislation and on ideas advocated by other discourse communities, articulated with redefined legal principles - an effort towards authorizing the official reasoning in favor of the relevance in keeping the decentralization process under the control of the federal administration. The analysis concludes that an infra-legal standard can neither grant state and federal administrations a hierarchical superiority (mediation function) over municipal administrations, nor can it transfer the legal responsibilities pertaining to Health Councils over to inter-administration commissions (Comissões Intergestores) , thus making the former mere decision ratifiers. This study found that granting privileges not contemplated in the legislation to state and federal administrations surfaced again and more strongly so in 2001 in yet another operating standard.

Multiagency exercises were an important part of the development of the Federal Radiological Emergency Response Plan. This paper concentrates on two of these exercises, the Federal Field Exercise in March 1984 and the Relocation Tabletop Exercise in December 1985. The Federal Field Exercise demonstrated the viability and usefulness of the draft plan; lessons learned from the exercise were incorporated into the published plan. The Relocation Tabletop Exercise examined the federal response in the postemergency phase. This exercise highlighted the change over time in the roles of some agencies and suggested response procedures that should be developed or revised. 8 refs

Draft Federal Act of the Russian Federation 'The Civil Liability for Nuclear Damage and its Financial Security'

International Nuclear Information System (INIS)

Lebedeva, Yulia

2014-01-01

The use of nuclear power by states in the modern world requires supplements to international law through the development of national legislation on civil liability for nuclear damage and compensation. The situation in the Russian Federation is no exception. Russian law on civil liability for nuclear damage has not fully evolved, and currently, there is no specific law covering liability for nuclear damage, nor is there a law regarding the financial and insurance mechanisms for compensation. Instead, the current laws establish a state system of benefits and compensation for damage to health and property of citizens. Since 1996, Russia has been actively working to develop a draft federal act to cover liability for nuclear damage. A bill was first introduced in the State Duma of the Federal Assembly of the Russian Federation on 16 July 1996, and was originally called 'The Compensation for Nuclear Damage and Nuclear Insurance'. In 1997, the official representative of the Government of the Russian Federation, Head of Russian Federal Inspectorate for Nuclear and Radiation Safety, Yuri Vishnevsky, was appointed to present this bill for discussion in the chambers of the Federal Assembly of the Russian Federation. In September 1998, the State Duma rejected the draft federal act and instead adopted in the first reading a different draft federal act: No. 96700118-2, 'The Civil Liability for Nuclear Damage and its Financial Security' ('the bill'). In this case, the State Duma Committee on Ecology was charged with incorporating the incoming amendments into a final bill and submitting it to the State Duma for a second reading. In 2005, Russia ratified the Vienna Convention on Civil Liability for Nuclear Damage. This ratification required significant amendments to 'The Civil Liability for Nuclear Damage and its Financial Security' bill. But, even though the Russian Federation had not yet ratified the Vienna Convention, the drafters were still careful to take into account the

The presence of high amounts of lactic acid in acid whey restricts its ability to be further processed because lactose appears to remain in its amorphous form. A systematic study is lacking in this regard especially during the concentration step. Hence, the main aim of the study was to establish the structure and behavior of water molecules surrounding lactose in the presence of 1% (wt/wt) lactic acid at a concentration up to 50% (wt/wt). Furthermore, the crystallization nature of freeze-dried lactose with or without lactic acid was established using differential scanning calorimetry and Fourier transform infrared spectroscopy. Two mechanisms were proposed to describe the behavior of water molecules around lactose molecules during the concentration of pure lactose and lactose solutions with lactic acid. Pure lactose solution exhibited a water evaporation enthalpy of ~679 J·g(-1), whereas lactose+ lactic acid solution resulted in ~965 J·g(-1) at a 50% (wt/wt) concentration. This indicates a greater energy requirement for water removal around lactose in the presence of lactic acid. Higher crystallization temperatures were observed with the presence of lactic acid, indicating a delay in crystallization. Furthermore, less crystalline lactose (~12%) was obtained in the presence of lactic acid, indicating high amorphous nature compared with pure lactose where ~50% crystallinity was obtained. The Fourier transform infrared spectra revealed that the strong hydration layer consisting lactic acid and H3O(+) ions surrounded lactose molecules via strong H bonds, which restricted water mobility, induced a change in structure of lactose, or both, creating unfavorable conditions for lactose crystallization. Thus, partial or complete removal of lactic acid from acid whey may be the first step toward improving the ability of acid whey to be processed. Copyright © 2015 American Dairy Science Association.

Viscosity calculated in simulations of strongly coupled dusty plasmas with gas friction

International Nuclear Information System (INIS)

Feng Yan; Goree, J.; Liu Bin

2011-01-01

A two-dimensional strongly coupled dusty plasma is modeled using Langevin and frictionless molecular dynamical simulations. The static viscosity η and the wave-number-dependent viscosity η(k) are calculated from the microscopic shear in the random motion of particles. A recently developed method of calculating the wave-number-dependent viscosity η(k) is validated by comparing the results of η(k) from the two simulations. It is also verified that the Green-Kubo relation can still yield an accurate measure of the static viscosity η in the presence of a modest level of friction as in dusty plasma experiments.

DNA origami represent powerful platforms for single-molecule investigations of biomolecular processes. The required structural integrity of the DNA origami may, however, pose significant limitations regarding their applicability, for instance in protein folding studies that require strongly denaturing conditions. Here, we therefore report a detailed study on the stability of 2D DNA origami triangles in the presence of the strong chaotropic denaturing agents urea and guanidinium chloride (GdmCl) and its dependence on concentration and temperature. At room temperature, the DNA origami triangles are stable up to at least 24 h in both denaturants at concentrations as high as 6 M. At elevated temperatures, however, structural stability is governed by variations in the melting temperature of the individual staple strands. Therefore, the global melting temperature of the DNA origami does not represent an accurate measure of their structural stability. Although GdmCl has a stronger effect on the global melting temperature, its attack results in less structural damage than observed for urea under equivalent conditions. This enhanced structural stability most likely originates from the ionic nature of GdmCl. By rational design of the arrangement and lengths of the individual staple strands used for the folding of a particular shape, however, the structural stability of DNA origami may be enhanced even further to meet individual experimental requirements. Overall, their high stability renders DNA origami promising platforms for biomolecular studies in the presence of chaotropic agents, including single-molecule protein folding or structural switching.

Synchronisation hubs in the visual cortex may arise from strong rhythmic inhibition during gamma oscillations.

Neurons in the visual cortex exhibit heterogeneity in feature selectivity and the tendency to generate action potentials synchronously with other nearby neurons. By examining visual responses from cat area 17 we found that, during gamma oscillations, there was a positive correlation between each unit's sharpness of orientation tuning, strength of oscillations, and propensity towards synchronisation with other units. Using a computational model, we demonstrated that heterogeneity in the strength of rhythmic inhibitory inputs can account for the correlations between these three properties. Neurons subject to strong inhibition tend to oscillate strongly in response to both optimal and suboptimal stimuli and synchronise promiscuously with other neurons, even if they have different orientation preferences. Moreover, these strongly inhibited neurons can exhibit sharp orientation selectivity provided that the inhibition they receive is broadly tuned relative to their excitatory inputs. These results predict that the strength and orientation tuning of synaptic inhibition are heterogeneous across area 17 neurons, which could have important implications for these neurons' sensory processing capabilities. Furthermore, although our experimental recordings were conducted in the visual cortex, our model and simulation results can apply more generally to any brain region with analogous neuron types in which heterogeneity in the strength of rhythmic inhibition can arise during gamma oscillations. © 2013 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.

The CAAA maintains existing state and federal commission jurisdiction for the oversight of utility compliance with emissions trading provisions. With existing state and federal jurisdictions maintained, the CAAA creates a new opportunity for state commissions to cooperate among themselves and with the FERC. Should this opportunity not be realized, a new area of jurisdictional conflict could result. This section describes options for regional regulation and the tax treatment of allowances. 20 refs

In this work, experiments and modeling for the interactions between uranyl ion and GMZ bentonite in the presence of fulvic acid are presented. The results demonstrated that FA is strongly bound to GMZ bentonite, and these molecules have a very large effect on the U(VI) sorption. The results also demonstrated that U(VI) sorption to GMZ bentonite in the presence and absence of sorbed FA can be well predicted by combining SHM and DLM. According to the model calculations, the nature of the interactions between FA with U(VI) at GMZ bentonite surface is mainly surface complex.

Politics of the U.S. Federal budget process.

Science.gov (United States)

Elwood, Thomas W

U.S. Congress members are influenced in three ways: 1) through the acquisition of money to finance political campaigns; 2) by acquiring enough votes to enable them to be reelected; and 3) obtaining expert information on topics of personal interest. Federal spending patterns have a strong impact on the first two items. The ability to funnel money into a congressional district or state provides an excellent opportunity for a legislator to remain in office. Congress often appears to be highly irrational but individual legislators find it in their rational self-interest to behave in ways that are detrimental to the collective interest of Congress as an institution and to the collective good of society. Every year, leaders of both parties begin a legislative session with the intention of producing both a concurrent budget resolution and a set of spending bills according to schedule. Usually, they fail dismally. This article discusses the reasons why such failures tend to occur regularly.

We reconsider the observed CMB dipolar asymmetry in the context of open inflation, where a supercurvature mode might survive the bubble nucleation. If such a supercurvature mode modulates the amplitude of the curvature power spectrum, it would easily produce an asymmetry in the power spectrum. We show that current observational data can be accommodated in a three-field model, with simple quadratic potentials and a non-trivial field-space metric. Despite the presence of three fields, we believe this model is so far the simplest that can match current observations. We are able to match the observed strong scale dependence of the dipolar asymmetry, without a fine tuning of initial conditions, breaking slow roll or adding a feature to the evolution of any field.

Mycoplasma hyopneumoniae (M. hyo) and Porcine Circovirus Type 2 (PCV2) are major pathogens that cause significant health problems in swine worldwide. Maternal derived immunity (MDI) has been suggested as a significant immediate defence factor for newborn piglets and may interfere with piglet's vaccination-induced immunity. The study aimed to assess the efficacy of a novel combination vaccine (consisting of PCV2 subunits and inactivated M. hyo strain J), against PCV2 and M. hyo natural infection [Porcilis ® PCV M Hyo (MSD Animal Health, Boxmeer, the Netherlands)], in the presence of strong maternally derived PCV2 immunity (antibody titre averaged 11.08 log 2 ), under field conditions. The study was performed according to a controlled, randomized and blinded design in a Greek swine unit with Enzootic Pneumonia (EP) and subclinical PCV2 infection. In total, 600 healthy three-week-old suckling piglets were allocated randomly, either to treatment (vaccinated with the test product) or control group (injected with sterile buffered saline). Vaccination significantly reduced the severity of lung lesions at slaughter (lesions of cranio-ventral pulmonary consolidation) (P pigs. Furthermore, 25 g higher average daily weight gain (ADWG) was observed during the finishing phase (P < 0.001) and 18 g greater ADWG overall (P < 0.001). Results of LLS, PCV2 viremia and ADWG support the test product's efficacy in the face of strong maternally derived PCV2 immunity.

Radioactive waste in Federal Germany

International Nuclear Information System (INIS)

Brennecke, P.; Schumacher, J.; Warnecke, E.

1988-01-01

The Physikalisch-Technische Bundesanstalt (PTB) is responsible for the long-term storage and disposal of radioactive waste according to the Federal Atomic Energy Act. On behalf of the Federal Minister of the Environment, Nature Conservation and Nuclear Safety, since 1985, the PTB has been carrying out annual inquiries into the amounts of radioactive waste produced in the Federal Republic of Germany. Within the scope of this inquiry performed for the preceding year, the amounts of unconditioned and conditioned waste are compiled on a producer- and plant-specific basis. On the basis of the inquiry for 1986 and of data presented to the PTB by the waste producers, future amounts of radioactive waste have been estimated up to the year 2000. The result of this forecast is presented. In the Federal Republic of Germany two sites are under consideration for disposal of radioactive waste. In the abandoned Konrad iron mine in Salzgitter-Bleckenstedt it is intended to dispose of such radioactive waste which has a negligible thermal influence upon the host rock. The Gorleben salt dome is being investigated for its suitability for the disposal of all kinds of solid and solidified radioactive wastes, especially of heat-generating waste. Comparing the estimated amount of radioactive wastes with the capacity of both repositories it may be concluded that the Konrad and Gorleben repositories will provide sufficient capacity to ensure the disposal of all kinds of radioactive waste on a long-term basis in the Federal Republic of Germany. 1 fig., 2 tabs

The Federal Features of the EU: Lessons from Canada

Directory of Open Access Journals (Sweden)

Amy Verdun

2016-08-01

Full Text Available There has been a rise and fall in interest in federalism in the context of European integration. This article assesses the federal nature of the EU. It draws in particular on the work of Michael Burgess who has been one of the key thinkers on this issue. Because there are many types of ‘federalisms’ available across the globe, it is helpful to make a comparison with another political system to offer a base line. In this article I explore to what extent the EU already has federal features. With the help of the work of Burgess I seek to look beyond the specific characteristics of the EU and reflect on how a comparison with this other polity can offer us insights into what is going on within the EU political system. Drawing on the comparison with Canada, I seek to identify the characteristics of the EU that are already those of a federation. Therefore, the guiding question of this article is: compared to Canada, what particular features does the EU have that reminds us of a federation and what features is it still lacking? It finds that the EU has a considerable amount of federal features (federation, but that a federal tradition, a federal ideology and advocacy to a federal goal (federalism are mostly absent.

Hall effect in a strong magnetic field: Direct comparisons of compressible magnetohydrodynamics and the reduced Hall magnetohydrodynamic equations

International Nuclear Information System (INIS)

Martin, L. N.; Dmitruk, P.; Gomez, D. O.

2010-01-01

In this work we numerically test a model of Hall magnetohydrodynamics in the presence of a strong mean magnetic field: the reduced Hall magnetohydrodynamic model (RHMHD) derived by [Gomez et al., Phys. Plasmas 15, 102303 (2008)] with the addition of weak compressible effects. The main advantage of this model lies in the reduction of computational cost. Nevertheless, up until now the degree of agreement with the original Hall MHD system and the range of validity in a regime of turbulence were not established. In this work direct numerical simulations of three-dimensional Hall MHD turbulence in the presence of a strong mean magnetic field are compared with simulations of the weak compressible RHMHD model. The results show that the degree of agreement is very high (when the different assumptions of RHMHD, such as spectral anisotropy, are satisfied). Nevertheless, when the initial conditions are isotropic but the mean magnetic field is maintained strong, the results differ at the beginning but asymptotically reach a good agreement at relatively short times. We also found evidence that the compressibility still plays a role in the dynamics of these systems, and the weak compressible RHMHD model is able to capture these effects. In conclusion the weak compressible RHMHD model is a valid approximation of the Hall MHD turbulence in the relevant physical context.

We report on a new approach for magnetic imaging, highly sensitive even in the presence of external, strong magnetic fields. Based on FIB-assisted fabricated high-aspect-ratio rare-earth nanomagnets, we produce groundbreaking magnetic force tips with hard magnetic character where we combine a high aspect ratio (shape anisotropy) together with strong crystalline anisotropy (rare-earth-based alloys). Rare-earth hard nanomagnets are then FIB-integrated to silicon microcantilevers as highly sharpened tips for high-field magnetic imaging applications. Force resolution and domain reversing and recovery capabilities are at least one order of magnitude better than for conventional magnetic tips. This work opens new, pioneering research fields on the surface magnetization process of nanostructures based either on relatively hard magnetic materials—used in magnetic storage media—or on materials like superparamagnetic particles, ferro/antiferromagnetic structures or paramagnetic materials.

Drenagem interna como fator de diferenciação de Latossolos do Distrito Federal The internal drainage as a differentiation factor in Oxisols of Distrito Federal, Brazil

, the water-table oscillation was monitored using 2.5-m depth observation wells, during one year. The studied Oxisols were considered chemically and physically similar. However, they differed as to morphological and mineralogical characterization, with the presence of concretionary horizons and goethite in the LVA. Goethite stability in this soils was influenced by the water-table oscillation. The presence of concretionry horizons in LVA caused an internal drainage deficiency, which resulted in lower saturated hydraulic conductivity and lower variation of the water-table levels. Therefore, LVA soils show lower agricultural potential than LV ones, in Distrito Federal. Oxisols physicohydric characteristics have little influence on soil diagnostic attributes, except for iron oxides mineralogy, which show increased contents of goethite in low internal drainage conditions.

Instabilities in strongly coupled plasmas

CERN Document Server

Kalman, G J

2003-01-01

The conventional Vlasov treatment of beam-plasma instabilities is inappropriate when the plasma is strongly coupled. In the strongly coupled liquid state, the strong correlations between the dust grains fundamentally affect the conditions for instability. In the crystalline state, the inherent anisotropy couples the longitudinal and transverse polarizations, and results in unstable excitations in both polarizations. We summarize analyses of resonant and non-resonant, as well as resistive instabilities. We consider both ion-dust streaming and dust beam-plasma instabilities. Strong coupling, in general, leads to an enhancement of the growth rates. In the crystalline phase, a resonant transverse instability can be excited.

VNTR-typing of Vibrio cholerae strains isolated in the territory of Russian Federation in 2012. 71 Vibrio cholerae O3 and 3 V cholerae O1/O139 strains were used in the study. Genotyping was performed by using PCR for 5 VNTR-loci. Multilocus VNTR-typing allowed to group the strains into 31 VNTR-genotypes. Genotypes were divided among 10 discrete clusters by results of a cluster analysis. The presence of tcpA gene is clearly linked with the presence of VcB locus. Each geographic region was characterized by their own VNTR-genotypes. In the course of the carried out VNTR-genotyping of V. cholerae isolated in 2012, 2 types of vibrio population formation were detected. A geographic attachment to specific regions was characteristic for most of the genotypes.

Federal Law "On Prosecutor's Office of the Russian Federation": Conditions of Adoption and Development Trends

At this time, revealed numerous violations. Prosecution authorities stood on the position of the rule of law and the interests of the state, has become a serious obstacle to the forces that destroy the state and its economy. In the 90 years of the twentieth century, the prosecutor's office declined status in the society, which is reflected in the text of the new Constitution of the Russian Federation (1993, containing only one, 129 article devoted to the prosecuting authorities, while there were five (Article in the Constitution of the USSR of such articles . 164, 165, 166, 167, 168. Also, the law "On the Prosecutor's Office of the Russian Federation" does not include an article on the problems of supervision in this direction, as well as Art. 30 "to arrest". These changes to the law the prosecutor's office indicate the desire of the legislator to downplay the independence of the prosecution and its role in countering the massive violation of the law of the initial period of "perestroika". The role of politics in the legal regulation of the activities of the prosecutor's office is determined by the law "On the Prosecutor's Office of the Russian Federation" and the insertion in the amended. The activities of the prosecution authorities, the powers of prosecutors are regulated by criminal procedure, civil procedure, arbitration procedure and other legislation, which varies due to the effects of many political reasons.

State-federal interactions in nuclear regulation

Energy Technology Data Exchange (ETDEWEB)

Pasternak, A.D.; Budnitz, R.J.

1987-12-01

The Atomic Energy Act of 1954 established, and later Congressional amendments have confirmed, that except in areas which have been explicitly granted to the states, the federal government possesses preemptive authority to regulate radiation hazards associated with the development and use of atomic energy. Since the passage of the original Act, numerous decisions by the courts have reaffirmed the legitimacy of federal preemption, and have defined and redefined its scope. In this study, the aim is to explore the underlying issues involved in federal preemption of radiation-hazard regulation, and to recommend actions that the Department of Energy and other agencies and groups should consider undertaking in the near term to protect the preemption principle. Appropriate roles of the states are discussed, as well as recent state-level activities and their rationale, and several current arenas in which state-federal conflicts about regulation of hazards are being played out. The emphasis here is on four particular arenas that are now important arenas of conflict, but the issues discussed are far broader in scope. These four arenas are: state-level moratorium activity; emergency planning for reactors; conflicts arising from state financial regulation; and inroads in federal preemption through litigation under state law.

The efficiency of Amberjet 4200 resin in removing nitrate in the presence of competitive anions from Shiraz drinking water.

Science.gov (United States)

Dehghani, M; Haghighi, A Binaee; Zamanian, Z

2010-06-01

The aim of this research is to study the feasibility of removing nitrates from water by means of anion exchange. In the purposed work an attempt was made to utilize strong basic anion resin to remove nitrate in the presence of competitive anion. Amberjet Cl- 4200 ion exchange resin was used in a batch scale. The fixation rate of nitrate without the presences of any competitive anion was almost constant (94.60-96.43) when the nitrate concentrations are in the range of 100-150 mg L(-1). The fixation rate of nitrate in the presences of two competitive anions (sulphate and chloride) was reduced to 82% when the concentration of nitrate was 100 mg L(-1).

The tightness of control procedures in the legal protection provided by jurisdiction against directives issued by the Federal Government - a problem of competence distribution between the Federal Constitutional Court and the Federal Administrative Court?

International Nuclear Information System (INIS)

Zimmermann, B.

1992-01-01

The tightness of control procedures in the legal protection provided by jurisdiction against directives issued by the Federal Government - a problem of competence distribution between the Federal Constitutional Court and the Federal Administrative Court? The article examines questions of recourse to the competent court, problems concerning the admissibility of legal proceedings before the Federal Admininstrative Court, the competence of the Laender in performing administrative acts on behalf of the Federation, the effectiveness of legal protection and the relationship between the Laender and the Federation in terms of responsibility for constitutional rights. The legal protection offered by administrative law, against a directive of the Federal Government is wholly ineffective, as there is no legal position a Land could bring into play to defened itself against a directive leading to unlawful action. Inequites which thus occur can however be met via a dispute between the Federation and the Laender as provided by the constitution, as the content of a directive becomes relevant in attempts to exert influence on the competence issue. Ultimately the rulings of the Basic Law on competence serve to protect the citizen and the community against excesses. In this connection the constitutional rights in their capacity as negative competence rulings disqualify executive acts. (orig./HSCH) [de

The Political Economy of Federally Sponsored Data

Directory of Open Access Journals (Sweden)

Bart Ragon

2013-11-01

Full Text Available Librarian involvement in the Open Access (OA movement has traditionally focused on access to scholarly publications. Recent actions by the White House have focused attention on access on the data produced from federally sponsored research. Questions have emerged concerning access to the output of federally sponsored research and whether it is a public or private good. Understanding the political battle over access to federally funded research is closely tied to the ownership of the peer review process in higher education and associated revenue streams, and as a result, interest groups seeking to influence government regulation have politicized the issues. As a major funder of research in higher education, policies from the federal government are likely to drive change in research practices at higher education institutions and impact library services. The political economy of federally sponsored research data will shape research enterprises in higher education inspire a number of new services distributed throughout the research life cycle.

Lighting technology specifications for relighting federal buildings

International Nuclear Information System (INIS)

Harris, L.; Purcell, C.W.; Gordon, H.; McKay, H.

1993-01-01

The Department of Energy's Federal Relighting Initiative, under the Federal Energy Management Program (FEMP), now offers a comprehensive process to assist agencies in meeting the DOE energy mandate that states that Federal facilities shall use 20% less energy by the year 2000, based on 1985 consumption, and shall improve lighting to increase productivity with relighting projects. The process provides a systematic approach in the screening, selection, design, implementation and evaluation of relighting projects. The Master Specifications help assure the acquisition of high-quality, life-cycle cost-effective lighting systems. The process begins with the screening of the agency's building stock to identify the most promising relighting candidates and concludes with implementation support and system performance assessment. The tools developed by FRI are designed to assist agencies during each phase of the relighting process. The tools are based upon the Federal life-cycle cost approach, thereby complying with 10 CFR, part 436, and the Federal life-cycle cost requirement

Federalism and health policy.

Science.gov (United States)

Nathan, Richard P

2005-01-01

This paper presents a cyclical theory of U.S. federalism and social policy: Many social policy initiatives are tested and refined at the state level, especially during conservative periods, and later morph into national policies. The paper describes such federalism cycles and offers an interpretation of why and how they occur, focusing on Medicaid. State activism has preserved and expanded Medicaid through policy innovation and resistance to retrenchment, especially in conservative periods, by taking advantage of the flexibility the program provides. I conclude that Medicaid's incremental/partnership approach is appropriate and feasible to build on for a future expansion of health care coverage.

Debunking vaccination myths: strong risk negations can increase perceived vaccination risks.

Science.gov (United States)

Betsch, Cornelia; Sachse, Katharina

2013-02-01

Information about risks is often contradictory, especially in the health domain. A vast amount of bizarre information on vaccine-adverse events (VAE) can be found on the Internet; most are posted by antivaccination activists. Several actors in the health sector struggle against these statements by negating claimed risks with scientific explanations. The goal of the present work is to find optimal ways of negating risk to decrease risk perceptions. In two online experiments, we varied the extremity of risk negations and their source. Perception of the probability of VAE, their expected severity (both variables serve as indicators of perceived risk), and vaccination intentions. Paradoxically, messages strongly indicating that there is "no risk" led to a higher perceived vaccination risk than weak negations. This finding extends previous work on the negativity bias, which has shown that information stating the presence of risk decreases risk perceptions, while information negating the existence of risk increases such perceptions. Several moderators were also tested; however, the effect occurred independently of the number of negations, recipient involvement, and attitude. Solely the credibility of the information source interacted with the extremity of risk negation: For credible sources (governmental institutions), strong and weak risk negations lead to similar perceived risk, while for less credible sources (pharmaceutical industries) weak negations lead to less perceived risk than strong negations. Optimal risk negation may profit from moderate rather than extreme formulations as a source's trustworthiness can vary.

Federalism and regional health care expenditures: an empirical analysis for the Swiss cantons.

Science.gov (United States)

Crivelli, Luca; Filippini, Massimo; Mosca, Ilaria

2006-05-01

Switzerland (7.2 million inhabitants) is a federal state composed of 26 cantons. The autonomy of cantons and a particular health insurance system create strong heterogeneity in terms of regulation and organisation of health care services. In this study we use a single-equation approach to model the per capita cantonal expenditures on health care services and postulate that per capita health expenditures depend on some economic, demographic and structural factors. The empirical analysis demonstrates that a larger share of old people tends to increase health costs and that physicians paid on a fee-for-service basis swell expenditures, thus highlighting a possible phenomenon of supply-induced demand.

Green Roofs: Federal Energy Management Program (FEMP) Federal Technology Alert

Energy Technology Data Exchange (ETDEWEB)

Scholz-Barth, K.; Tanner, S.

2004-09-01

In a ''green roof,'' a layer of vegetation (e.g., a roof garden) covers the surface of a roof to provide shade, cooler indoor and outdoor temperatures, and effective storm-water management to reduce runoff. The main components are waterproofing, soil, and plants. There are two basic kinds: intensive and extensive. An intensive green roof often features large shrubs and trees, and it can be expensive to install and maintain. An extensive green roof features shallow soil and low-growing, horizontally spreading plants that can thrive in the alpine conditions of many rooftops. These plants do not require a lot of water or soil, and they can tolerate a significant amount of exposure to the sun and wind. This Federal Technology Alert focuses on the benefits, design, and implementation of extensive green roofs and includes criteria for their use on federal facilities.

Holstein-Primakoff representation and supercoherent states for strongly correlated electron systems

International Nuclear Information System (INIS)

Azakov, S.

1999-09-01

First we show that the algebra of operators entering the Hamiltonian of the t-J model describing the strongly correlated electron system is graded spl(2.1) algebra. Then after a brief discussion of its atypical representations we construct the Holstein-Primakoff nonlinear realization of these operators which allows to carry out the systematic semiclassical approximation, similarly to the spin-wave theory of localized magnetism. The fact that the t-J model describes the itinerant magnetism is reflected in the presence of the spinless fermions. For the supersymmetric spl(2.1) algebra the supercoherent states are proposed and the partition function of the t-J model is represented as a path integral with the help of these states. (author)

Hanle Magnetoresistance in Thin Metal Films with Strong Spin-Orbit Coupling.

Vélez, Saül; Golovach, Vitaly N; Bedoya-Pinto, Amilcar; Isasa, Miren; Sagasta, Edurne; Abadia, Mikel; Rogero, Celia; Hueso, Luis E; Bergeret, F Sebastian; Casanova, Fèlix

2016-01-08

We report measurements of a new type of magnetoresistance in Pt and Ta thin films. The spin accumulation created at the surfaces of the film by the spin Hall effect decreases in a magnetic field because of the Hanle effect, resulting in an increase of the electrical resistance as predicted by Dyakonov [Phys. Rev. Lett. 99, 126601 (2007)]. The angular dependence of this magnetoresistance resembles the recently discovered spin Hall magnetoresistance in Pt/Y(3)Fe(5)O(12) bilayers, although the presence of a ferromagnetic insulator is not required. We show that this Hanle magnetoresistance is an alternative simple way to quantitatively study the coupling between charge and spin currents in metals with strong spin-orbit coupling.

James Dwight Dana and John Strong Newberry in the US Pacific Northwest: The roots of American fluvialism

Science.gov (United States)

O'Connor, Jim E.

2018-01-01

Recognition of the power of rivers to carve landscapes transformed geology and geomorphology in the late nineteenth century. Wide acceptance of this concept—then known as “fluvialism”—owes to many factors and people, several associated with exploration of western North America. Especially famous are the federal geographic and geologic surveys of the US Southwest with John Wesley Powell and Grove Karl Gilbert, which produced key insights regarding river processes. Yet earlier and less-known surveys also engaged young geologists embarking on tremendously influential careers, particularly the 1838–1842 US Exploring Expedition with James Dwight Dana and the 1853–1855 railroad surveys including John Strong Newberry. Informed but little constrained by European and British perspectives on landscape formation, Dana and Newberry built compelling cases for the erosive power of rivers, largely from observations in the US Pacific Northwest. They seeded the insights of the later southwestern surveys, Dana by his writings and station at Yale and his hugely influential Manual of Geology, published in 1863, and Newberry by becoming the first geologist to explore the dramatic river-carved canyons of the Southwest and then a forceful proponent of the federal surveys spotlighting the erosional landscapes. Newberry also gave Gilbert his start as a geologist. Although Dana and Newberry are renowned early American geologists, their geomorphic contributions were overshadowed by the works of Powell, Gilbert, and William Morris Davis. Yet Dana and Newberry were the first ardent American proponents of fluvialism, providing strong roots that in just a few decades transformed western geology, roots nourished in large measure by the geologically fertile landscapes of the US Pacific Northwest.

A new direction for prioritizing federal agency cleanups

International Nuclear Information System (INIS)

McCrillis, L.

1995-01-01

Departments and agencies of the federal government manage a vast array of activities at 27,000 facilities. Due to the nature of such activities, federal facilities could be contaminated with hazardous substances. It is estimated that the federal government ultimately will be responsible for or have a significant role in the cleanup of up to 500,000 sites. Although federal facilities comprise only a small percentage of the community regulated under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), federal facilities owned or operated by the Department of Energy (DOE) and the Department of Defense (DOD) are usually larger and more complex than their private industrial counterparts. Federal facilities routinely have a larger number of sites on their facilities with varying degrees of risk. At present, the approaches for allocating resources for environmental restoration of federal facilities, for incorporating stakeholder concerns in the allocation, and for obtaining funding from Congress vary greatly from one agency to another. In light of these concerns, the federal government recognizes the need to evaluate the current resource allocation system for funding remediation projects and to establish a broader-based publicly supported priority-setting method. This paper outlines a possible new direction and summarizes the conclusions reached in a handful of forums created to address the issue of priority setting

ESR modes in a Strong-Leg Ladder in the Tomonaga-Luttinger Liquid Phase

Science.gov (United States)

Zvyagin, S.; Ozerov, M.; Maksymenko, M.; Wosnitza, J.; Honecker, A.; Landee, C. P.; Turnbull, M.; Furuya, S. C.; Giamarchi, T.

Magnetic excitations in the strong-leg quantum spin ladder compound (C7H10N)2CuBr4 (known as DIMPY) in the field-induced Tomonaga-Luttinger spin liquid phase are studied by means of high-field electron spin resonance (ESR) spectroscopy. The presence of a gapped ESR mode with unusual non-linear frequency-field dependence is revealed experimentally. Using a combination of analytic and exact diagonalization methods, we compute the dynamical structure factor and identify this mode with longitudinal excitations in the antisymmetric channel. We argue that these excitations constitute a fingerprint of the spin dynamics in a strong-leg spin-1/2 Heisenberg antiferromagnetic ladder and owe its ESR observability to the uniform Dzyaloshinskii-Moriya interaction. This work was partially supported by the DFG and Helmholtz Gemeinschaft (Germany), Swiss SNF under Division II, and ERC synergy UQUAM project. We acknowledge the support of the HLD at HZDR, member of the European Magnetic Field Laboratory (EMFL).

Executive Order 13693: Planning for Federal Sustainability in the Next Decade; Guidance for Federal Agencies on Executive Order 13693 -- Federal Fleet Management

Energy Technology Data Exchange (ETDEWEB)

2017-01-01

The U.S. Department of Energy (DOE) and U.S. General Services Administration (GSA) are issuing comprehensive guidance on the federal fleet requirements of Executive Order (E.O.) 13693, Planning for Federal Sustainability in the Next Decade (E.O. 13693), to help federal agencies subject to the executive order develop an overall approach for reducing total fleet greenhouse gas (GHG) emissions and fleet-wide per-mile GHG emissions, and ensure the approach helps these agencies meet their requirements. Three key GHG emissions reduction strategies - right-sizing fleets to mission, increasing fleet fuel efficiency, and displacing petroleum with alternative fuel use - are essential to meeting the requirements and are discussed further in this document. This guidance document is intended to help agency Chief Sustainability Officers (CSOs) and headquarters fleet managers craft tailored executable plans that achieve the purpose of E.O. 13693. The guidance will assist agencies in completing the first phase of a comprehensive fleet management framework by identifying the strategies each agency will then implement to meet or exceed its requirements.

2017-05-01

We give a non-perturbative construction of a distinguished state for the quantized Dirac field in Minkowski space in the presence of a time-dependent external field of the form of a plane electromagnetic wave. By explicit computation of the fermionic signature operator, it is shown that the Dirac operator has the strong mass oscillation property. We prove that the resulting fermionic projector state is a Hadamard state.

The presence of serum alters the properties of iron oxide nanoparticles and lowers their accumulation by cultured brain astrocytes

International Nuclear Information System (INIS)

Geppert, Mark; Petters, Charlotte; Thiel, Karsten; Dringen, Ralf

2013-01-01

Iron oxide nanoparticles (IONPs) are considered for various diagnostic and therapeutic applications. Such particles are able to cross the blood–brain barrier and are taken up into brain cells. To test whether serum components affect the properties of IONPs and/or their uptake into brain cells, we have incubated dimercaptosuccinate-coated magnetic IONPs without and with fetal calf serum (FCS) and have exposed cultured brain astrocytes with IONPs in the absence or presence of FCS. Incubation with FCS caused a concentration-dependent increase in the average hydrodynamic diameter of the particles and of their zeta-potential. In the presence of 10 % FCS, the diameter of the IONPs increased from 57 ± 2 to 107 ± 6 nm and the zeta-potential of the particles from −22 ± 5 to −9 ± 1 mV. FCS affected also strongly the uptake of IONPs by cultured astrocytes. The efficient time- and temperature-dependent cellular accumulation of IONPs was lowered with increasing concentration of FCS by up to 90 %. In addition, in the absence of serum, endocytosis inhibitors did not alter the IONP accumulation by astrocytes, while chlorpromazine or wortmannin lowered significantly the accumulation of IONPs in the presence of FCS, suggesting that clathrin-mediated endocytosis and macropinocytosis are involved in astrocytic IONP uptake from serum-containing medium. These data demonstrate that the presence of FCS strongly affects the properties of IONPs as well as their accumulation by cultured brain cells.

American and Canadian environmental federalism: A game-theoretic analysis

Energy Technology Data Exchange (ETDEWEB)

Gillroy, J.M.

1999-07-01

To understand why environmental federalism is different in Canada and the United States, one might begin with the initial strategic realities that faced the Fathers of Canadian Confederation and the Framers of the Constitution of the US. This essay examined federalism from a game theoretic point of view, to integrate and expose the rational properties of the decision to federate and the logical entailments of that choice for environmental policy within two specific strategic contexts. Specifically, the author suggests that American environmental federalism has arisen in response to the strategic reality of a prisoner's dilemma, while Canadian environmental federalism can be analyzed as an effort to regulate confrontations within a game of chicken. In addition to the analysis of each federated structure, evidence from five case studies demonstrates the usefulness of games to the study of comparative federalism.

The Bases of Federalism and Decentralization in Education

Directory of Open Access Journals (Sweden)

Carlos Ornelas

2003-05-01

Full Text Available This essay uses the Weberian-type ideal to define the conceptual bases of federalism and the decentralization of education. Classic federalism, ficticious federalism (corporativism, the origins and the indigenous version of the new federalism are discussed. We conclude that Mexican constitutional federalism is baroque and ambiguous. Based on theory and the experiences of various countries, bureaucratic centralism and its main characteristics are defined. As a contrast, a typology of educational decentralization is developed. Taken into account are its political, judicial and administrative definitions; a distinction is made between delegation and decentralization. It is argued that with the signing of the Agreement for the Modernization of Basic Education, the Mexican government sought to increase its legitimacy without losing control of education.

Effect of Dislocation Density on Deformation Behavior of Super Strong Bainitic Steel

Directory of Open Access Journals (Sweden)

B. Avishan

2017-02-01

Full Text Available Presence of nanoscale bainitic ferrites and high carbon retained austenites that are stable at ambient temperature within the microstructures of super strong bainitic steels makes it possible to achieve exceptional strengths and ductility properties in these groups of nanostructured steels. This article aims to study the effect of the dislocation density variations during tensile testing in ambient temperature on deformation behavior of nanostructured low temperature bainitic steels. Results indicate that dislocation absorption from bainitic ferrite subunits by surrounding retained austenite reduces the work hardening and therefore increases the formability of bainitic ferrite during deformation, which in turn results in a suitable combination of strength and ductility.

Strong-coupling theory of superconductivity

International Nuclear Information System (INIS)

Rainer, D.; Sauls, J.A.

1995-01-01

The electronic properties of correlated metals with a strong electron-phonon coupling may be understood in terms of a combination of Landau''s Fermi liquid theory and the strong-coupling theory of Migdal and Eliashberg. In these lecture notes we discuss the microscopic foundations of this phenomenological Fermi-liquid model of correlated, strong-coupling metals. We formulate the basic equations of the model, which are quasiclassical transport equations that describe both equilibrium and non-equilibrium phenomena for the normal and superconducting states of a metal. Our emphasis is on superconductors close to equilibrium, for which we derive the general linear response theory. As an application we calculate the dynamical conductivity of strong-coupling superconductors. (author)

Dynamics of bleomycin interaction with a strongly bound hairpin DNA substrate, and implications for cleavage of the bound DNA.

Science.gov (United States)

Bozeman, Trevor C; Nanjunda, Rupesh; Tang, Chenhong; Liu, Yang; Segerman, Zachary J; Zaleski, Paul A; Wilson, W David; Hecht, Sidney M

2012-10-31

Recent studies involving DNAs bound strongly by bleomycins have documented that such DNAs are degraded by the antitumor antibiotic with characteristics different from those observed when studying the cleavage of randomly chosen DNAs in the presence of excess Fe·BLM. In the present study, surface plasmon resonance has been used to characterize the dynamics of BLM B(2) binding to a strongly bound hairpin DNA, to define the effects of Fe(3+), salt, and temperature on BLM-DNA interaction. One strong primary DNA binding site, and at least one much weaker site, were documented. In contrast, more than one strong cleavage site was found, an observation also made for two other hairpin DNAs. Evidence is presented for BLM equilibration between the stronger and weaker binding sites in a way that renders BLM unavailable to other, less strongly bound DNAs. Thus, enhanced binding to a given site does not necessarily result in increased DNA degradation at that site; i.e., for strongly bound DNAs, the facility of DNA cleavage must involve other parameters in addition to the intrinsic rate of C-4' H atom abstraction from DNA sugars.

Strong Helioseismic Constraints on Weakly-Coupled Plasmas

Science.gov (United States)

Nayfonov, Alan

The extraordinary accuracy of helioseismic data allows detailed theoretical studies of solar plasmas. The necessity to produce solar models matching the experimental results in accuracy imposes strong constrains on the equations of state of solar plasmas. Several discrepancies between the experimental data and models have been successfully identified as the signatures of various non-ideal phenomena. Of a particular interest are questions of the position of the energy levels and the continuum edge and of the effect of the excited states in the solar plasma. Calculations of energy level and continuum shifts, based on the Green function formalism, appeared recently in the literature. These results have been used to examine effects of the shifts on the thermodynamic quantities. A comparison with helioseismic data has shown that the calculations based on lower-level approximations, such as the static screening in the effective two-particle wave equation, agree very well with the experimental data. However, the case of full dynamic screening produces thermodynamic quantities inconsistent with observations. The study of the effect of different internal partition functions on a complete set of thermodynamic quantities has revealed the signature of the excited states in the MHD (Mihalas, Hummer, Dappen) equation of state. The presence of exited states causes a characteristic 'wiggle' in the thermodynamic quantities due to the density-dependent occupation probabilities. This effect is absent if the ACTEX (ACTivity EXpansion) equation of state is used. The wiggle has been found to be most prominent in the quantities sensitive to density. The size of this excited states effect is well within the observational power of helioseismology, and very recent inversion analyses of helioseismic data seem to indicate the presence of the wiggle in the sun. This has a potential importance for the helioseismic determination of the helium abundance of the sun.

Relativistic quantum dynamics in strong fields: Photon emission from heavy, few-electron ions

International Nuclear Information System (INIS)

Fritzsche, S.; Stoehlker, T.

2005-03-01

Recent progress in the study of the photon emission from highly-charged heavy ions is reviewed. These investigations show that high-Z ions provide a unique tool for improving the understanding of the electron-electron and electron-photon interaction in the presence of strong fields. Apart from the bound-state transitions, which are accurately described in the framework of quantum electrodynamics, much information has been obtained also from the radiative capture of (quasi-) free electrons by high-Z ions. Many features in the observed spectra hereby confirm the inherently relativistic behavior of even the simplest compound quantum systems in nature. (orig.)

Regionalization and political dynamics of Brazilian health federalism.

Science.gov (United States)

Dourado, Daniel de Araujo; Elias, Paulo Eduardo Mangeon

2011-02-01

The implications from the Brazilian federal structure on the regionalization of health actions and services in the National Unified Health System (SUS) were analyzed, considering that the regional health planning in Brazil takes place within the context of intergovernmental relations as an expression of cooperative federalism in health. The analysis was based on a historical approach to Brazilian health federalism, recognizing two development periods, decentralization and regionalization. Regional health planning of SUS was explored in light of the theoretical framework of federalism. It is concluded that relative centralization of the process is needed in intergovernmental committees to actualize federal coordination and that it is essential to consider formalizing opportunities for dissent, both in regional management boards and in the intergovernmental committees, so that the consensus decision-making can be accomplished in healthcare regionalization.

Alkem instruction: Legal relief of a Federal State against instructions under the Atomic Energy Act issued by the Federal Government

International Nuclear Information System (INIS)

Steinberg, R.

1987-01-01

The German Federal Minister for the Environment, Protection of Nature, and Reactor Safety instructed the Hesse State Minister for Economics and Technology to grant the applications filed by Alkem GmbH for a first partial permit of the construction and operation of a fuel element factory, and to grant it on the basis of a draft working document discussed between the two ministries. The new feature is the refusal of the Hesse State Minister to follow these instructions. This has given rise to a conflict between the State and Federal Governments. The article deals with one aspect of the multifaceted legal controversy, i.e., the question of the possibilities of legal relief open to a Federal State against an instruction under the Atomic Energy Act issued by the Federal Government. First, the rank of this instruction within the scope of administration on behalf of the Federal Government will be discussed. Next, the central problem of the preconditions under which an instruction may violate rights of a Federal State will be investigated. Finally, the possibilities of litigation will be briefly referred to. (orig./HP) [de

Getting the job done: Resolving state-federal conflicts in Superfund

Energy Technology Data Exchange (ETDEWEB)

Smith, R.; Silver, D.

1998-12-31

The American system of federalism creates frequent opportunities for clashes between state and federal environmental regulators.State and federal environmental laws overlap but are not easily reconciled. Most federal environmental law provides no clear answer as to how to reconcile differing mandates of state and federal environmental regulators. In this article, they will examine these state-federal conflicts as they played out in 1994 in the cleanup of contaminated sites in the state of Washington. This article describes the way a regional office of the Environmental Protection Agency and the state`s Department of Ecology developed a novel approach to managing the essential tension between overlapping state and federal cleanup laws.

Reshaping the Federal System for a Postmodern Workforce

Directory of Open Access Journals (Sweden)

Daryl D. Green

2016-12-01

Full Text Available The federal government faces a human capital crisis over the next several years due to driving environmental forces, which include the reduction in the replacement labor force cohorts and the image problem of public service. One of the great challenges facing the federal service is the need to address the negative perceptions of the quality of work life experienced in the federal service, especially for younger employees. Consequently, governmental organizations must cope with increasing aging of their labor forces and elevated retirement levels exacerbating succession planning and knowledge transfer practices. This paper examines the current environment of the federal system and explores how it must adapt to postmodern influences that are embraced by Millennial and Generation X employees. While today’s federal system is rigid in many of its key leadership, performance management, and support service delivery systems, the postmodern workforce thrives on flexibility, involvement, and excitement. This paper further examines what leadership concepts and competencies can assist in the positive transformation of the federal government.

Lattice Hamiltonian approach to the Schwinger model. Further results from the strong coupling expansion

International Nuclear Information System (INIS)

Szyniszewski, Marcin; Manchester Univ.; Cichy, Krzysztof; Poznan Univ.; Kujawa-Cichy, Agnieszka

2014-10-01

We employ exact diagonalization with strong coupling expansion to the massless and massive Schwinger model. New results are presented for the ground state energy and scalar mass gap in the massless model, which improve the precision to nearly 10 -9 %. We also investigate the chiral condensate and compare our calculations to previous results available in the literature. Oscillations of the chiral condensate which are present while increasing the expansion order are also studied and are shown to be directly linked to the presence of flux loops in the system.

Elaboration of the recently proposed test of Pauli's principle under strong interactions

International Nuclear Information System (INIS)

Ktorides, C.N.; Myung, H.C.; Santilli, R.M.

1980-01-01

The primary objective of this paper is to stimulate the experimental verification of the validity or invalidity of Pauli's principle under strong interactions. We first outline the most relevant steps in the evolution of the notion of particle. The spin as well as other intrinsic characteristics of extended, massive, particles under electromagnetic interactions at large distances might be subjected to a mutation under additional strong interactions at distances smaller than their charge radius. These dynamical effects can apparently be conjectured to account for the nonpointlike nature of the particles, their necessary state of penetration to activate the strong interactions, and the consequential emergence of broader forces which imply the breaking of the SU(2)-spin symmetry. We study a characterization of the mutated value of the spin via the transition from the associative enveloping algebra of SU(2) to a nonassociative Lie-admissible form. The departure from the original associative product then becomes directly representative of the breaking of the SU(2)-spin symmetry, the presence of forces more general than those derivable from a potential, and the mutated value of the spin. In turn, such a departure of the spin from conventional quantum-mechanical values implies the inapplicability of Pauli's exclusion principle under strong interactions, because, according to this hypothesis, particles that are fermions under long-range electromagnetic interactions are no longer fermions under these broader, short-range, forces. In nuclear physics possible deviations from Pauli's exclusion principle can at most be very small. These experimental data establish that, for the nuclei considered, nucleons are in a partial state of penetration of their charge volumes although of small statistical character

Federalism and social justice: implications for social work.

Science.gov (United States)

Linhorst, Donald M

2002-07-01

Federalism is a system of government that divides power between two or more levels of government. During the current conservative political climate in the United States, power has shifted increasingly from the federal government to states, a move that has implications for the achievement of social justice. Consequently, it is now necessary for social workers to engage in political activity at the state and local levels, in addition to the federal level, to promote social justice. Implications for social work policy practice, research, and education for advancing social justice within the federal system of government are explored.

Health care, federalism and the new Social Union.

Science.gov (United States)

Wilson, K

2000-04-18

The Social Union framework agreement and the Health Accord provide examples of the close relationship that exists between federalism and the delivery of health care. These recent agreements represent a move from a federal-unilateral style of federalism to a more collaborative model. This shift will potentially affect federal funding for health care, interpretation of the Canada Health Act and the development of new health care initiatives. The primary advantage of the new collaborative model is protection of jurisdictional autonomy. Its primary disadvantages are blurring of accountability and potential for exclusion of the public from decision-making.

Impact of the strong electromagnetic field on the QCD effective potential for homogeneous Abelian gluon field configurations

International Nuclear Information System (INIS)

Galilo, Bogdan V.; Nedelko, Sergei N.

2011-01-01

The one-loop quark contribution to the QCD effective potential for the homogeneous Abelian gluon field in the presence of an external strong electromagnetic field is evaluated. The structure of extrema of the potential as a function of the angles between chromoelectric, chromomagnetic, and electromagnetic fields is analyzed. In this setup, the electromagnetic field is considered as an external one while the gluon field represents domain structured nonperturbative gluon configurations related to the QCD vacuum in the confinement phase. Two particularly interesting gluon configurations, (anti-)self-dual and crossed orthogonal chromomagnetic and chromoelectric fields, are discussed specifically. Within this simplified framework it is shown that the strong electromagnetic fields can play a catalyzing role for a deconfinement transition. At the qualitative level, the present consideration can be seen as a highly simplified study of an impact of the electromagnetic fields generated in relativistic heavy ion collisions on the strongly interacting hadronic matter.

Two sides of gender: ERP evidence for the presence of two routes during gender agreement processing.

Science.gov (United States)

Caffarra, Sendy; Janssen, Niels; Barber, Horacio A

2014-10-01

The present ERP study aimed at providing evidence for the existence of two routes in the brain for the processing of morphosyntactic features during language comprehension; a lexical route which retrieves grammatical properties stored in the lexicon without reliance on formal cues, and a form-based route that takes advantage of sub-lexical units strongly related to a specific grammatical class. In the experiment, we investigated grammatical gender agreement processing in Spanish article-noun word pairs using a grammaticality judgment task. Article-noun pairs either agreed or did not agree in gender. Noun transparency was manipulated such that the ending could be strongly associated with a specific gender class (i.e., transparent nouns) or not (i.e., opaque nouns). A visual half-field method was employed and ERPs were recorded in response to the target nouns in order to disentangle the initial hemisphere-specific computations of gender processing. ERP results showed that, while both hemispheres compute agreement dependencies, the left hemisphere is sensitive to the presence of formal gender cues at an early stage (i.e., 350-500 ms) indicating the presence of a form-based route. The right hemisphere showed an ERP effect of transparency, but later than the left hemisphere (i.e., 500-750 ms). These findings confirm the presence of two routes to gender, which can be differently used depending on the availability of transparent endings. In addition, the results showed hemispheric differences in the time course of the form-based route. Copyright © 2014 Elsevier Ltd. All rights reserved.

Self-channeling of high-power laser pulses through strong atmospheric turbulence

Science.gov (United States)

Peñano, J.; Palastro, J. P.; Hafizi, B.; Helle, M. H.; DiComo, G. P.

2017-07-01

We present an unusual example of truly long-range propagation of high-power laser pulses through strong atmospheric turbulence. A form of nonlinear self-channeling is achieved when the laser power is close to the self-focusing power of air and the transverse dimensions of the pulse are smaller than the coherence diameter of turbulence. In this mode, nonlinear self-focusing counteracts diffraction, and turbulence-induced spreading is greatly reduced. Furthermore, the laser intensity is below the ionization threshold so that multiphoton absorption and plasma defocusing are avoided. Simulations show that the pulse can propagate many Rayleigh lengths (several kilometers) while maintaining a high intensity. In the presence of aerosols, or other extinction mechanisms that deplete laser energy, the pulse can be chirped to maintain the channeling.

Nuclear supervision - federal executive administration or federal self-administration. From the view of an optimum task fulfillment

International Nuclear Information System (INIS)

Renneberg, W.

2005-01-01

The problem of the nuclear supervision, i.e. the question wether the federal executive administration can be considered a sustainable concept for the future within the framework of the atomic energy law is discussed in the paper. Without a complete refinancing of the nuclear supervision it is not possible to develop or at least keep a scientific and technical competence within the federal administration. In this context the results of the Kienbaum survey are reported. The objections and concerns with respect to the discussed federal self-administration model as alternative include possibly required changes of the constitutional law, aggravation of the loss of competence, the future of radiation protection, and interfaces to other fields of law, like emergency management

Plexcitons: The Role of Oscillator Strengths and Spectral Widths in Determining Strong Coupling

Energy Technology Data Exchange (ETDEWEB)

2018-01-05

Strong coupling interactions between plasmon and exciton-based excitations have been proposed to be useful in the design of optoelectronic systems. However, the role of various optical parameters dictating the plasmon-exciton (plexciton) interactions is less understood. Herein, we propose an inequality for achieving strong coupling between plasmons and excitons through appropriate variation of their oscillator strengths and spectral widths. These aspects are found to be consistent with experiments on two sets of free-standing plexcitonic systems obtained by (i) linking fluorescein isothiocyanate on Ag nanoparticles of varying sizes through silane coupling and (ii) electrostatic binding of cyanine dyes on polystyrenesulfonate-coated Au nanorods of varying aspect ratios. Being covalently linked on Ag nanoparticles, fluorescein isothiocyanate remains in monomeric state, and its high oscillator strength and narrow spectral width enable us to approach the strong coupling limit. In contrast, in the presence of polystyrenesulfonate, monomeric forms of cyanine dyes exist in equilibrium with their aggregates: Coupling is not observed for monomers and H-aggregates whose optical parameters are unfavorable. The large aggregation number, narrow spectral width, and extremely high oscillator strength of J-aggregates of cyanines permit effective delocalization of excitons along the linear assembly of chromophores, which in turn leads to efficient coupling with the plasmons. Further, the results obtained from experiments and theoretical models are jointly employed to describe the plexcitonic states, estimate the coupling strengths, and rationalize the dispersion curves. The experimental results and the theoretical analysis presented here portray a way forward to the rational design of plexcitonic systems attaining the strong coupling limits.

Adler-Bell-Jackiw anomaly and fermion-number breaking in the presence of a magnetic monopole

International Nuclear Information System (INIS)

Rubakov, V.A.

1982-01-01

In (V - A) theories, fermion number is broken in the presence of the 't Hooft-Polyakov magnetic monopole through the Adler-Bell-Jackiw anomaly. An exactly solvable zeroth-order approximation for evaluating Green functions of zero-angular-momentum fermions in the presence of a monopole is developed in the case of an SU(2) model with massless left-handed fermions. Within this approximation the density of the fermion-number breaking condensate is calculated. This density is found to be O(1), i.e. to be independent of the coupling constant and of the vacuum expectation value of the Higgs field. The corrections to the approximation are estimated. It is argued that the above effect can give rise to the strong baryon-number breaking in monopole-fermion interactions in SU(5) grand unified theory. (orig.)

A supersymmetric theory is constructed for a strong f plus a weak g graviton, together with their accompanying massive gravitinos, by gaugin the gradel 0Sp(2,2,1)x 0Sp(2,2,1) structure. The mixing term between f and g fields, which makes the strong graviton massive, can be introduced through a spontaneous symmetry-breaking mechanism implemented in this note by constructing a non-linear realization of the symmetry group

PREFACE: Strongly correlated electron systems Strongly correlated electron systems

Saxena, Siddharth S.; Littlewood, P. B.

2012-07-01

This special section is dedicated to the Strongly Correlated Electron Systems Conference (SCES) 2011, which was held from 29 August-3 September 2011, in Cambridge, UK. SCES'2011 is dedicated to 100 years of superconductivity and covers a range of topics in the area of strongly correlated systems. The correlated electronic and magnetic materials featured include f-electron based heavy fermion intermetallics and d-electron based transition metal compounds. The selected papers derived from invited presentations seek to deepen our understanding of the rich physical phenomena that arise from correlation effects. The focus is on quantum phase transitions, non-Fermi liquid phenomena, quantum magnetism, unconventional superconductivity and metal-insulator transitions. Both experimental and theoretical work is presented. Based on fundamental advances in the understanding of electronic materials, much of 20th century materials physics was driven by miniaturisation and integration in the electronics industry to the current generation of nanometre scale devices. The achievements of this industry have brought unprecedented advances to society and well-being, and no doubt there is much further to go—note that this progress is founded on investments and studies in the fundamentals of condensed matter physics from more than 50 years ago. Nevertheless, the defining challenges for the 21st century will lie in the discovery in science, and deployment through engineering, of technologies that can deliver the scale needed to have an impact on the sustainability agenda. Thus the big developments in nanotechnology may lie not in the pursuit of yet smaller transistors, but in the design of new structures that can revolutionise the performance of solar cells, batteries, fuel cells, light-weight structural materials, refrigeration, water purification, etc. The science presented in the papers of this special section also highlights the underlying interest in energy-dense materials, which

De Minimis Thresholds for Federal Building Metering Appropriateness

Energy Technology Data Exchange (ETDEWEB)

Henderson, Jordan W. [Pacific Northwest National Lab. (PNNL), Richland, WA (United States)

2015-03-31

The U.S. Department of Energy (DOE) is required by statute and Presidential Memorandum to establish guidelines for agencies to meter their Federal buildings for energy (electricity, natural gas, and steam) and water. See 42 U.S.C. § 8253(e). DOE issued guidance in February 2006 on the installation of electric meters in Federal buildings. A recent update to the 2006 guidance accounts for more current metering practices within the Federal Government. The updated metering guidance specifies that all Federal buildings shall be considered “appropriate” for energy or water metering unless identified for potential exclusion. In developing the updated guidance to carry out the statue, Congress also directed DOE to (among other things) establish exclusions from the metering requirements based on the de minimis quantity of energy use of a Federal building, industrial process, or structure. This paper discusses the method used to identify de minimis values.

Synthesis and strong photooxidation power of a supramolecular hybrid comprising a polyoxometalate and Ru(II) polypyridyl complex with zinc(II).

Ohashi, Kenji; Takeda, Hiroyuki; Koike, Kazuhide; Ishitani, Osamu

2015-01-01

A novel method for constructing supramolecular hybrids composed of polyoxometalates and photofunctional metal complexes was developed. A Ru(II) complex with phosphonate groups (RuP) strongly interacted with Zn(II) to afford a 2 : 1 trinuclear metal complex ([(RuP)2Zn](3+)). In dimethylsulfoxide, [(RuP)2Zn](3+) strongly interacted with a Keggin-type heteropolyoxometalate (Si-WPOM) to form a 1 : 1 hybrid ([(RuP)2Zn]-POM). Irradiation of [(RuP)2Zn]-POM in the presence of diethanolamine caused rapid accumulation of the one-electron reduced hybrid with a quantum yield of 0.99.

Persistence of pollination mutualisms in the presence of ants.

Science.gov (United States)

Wang, Yuanshi; Wang, Shikun

2015-01-01

This paper considers plant-pollinator-ant systems in which the plant-pollinator interaction is mutualistic but ants have both positive and negative effects on plants. The ants also interfere with pollinators by preventing them from accessing plants. While a Beddington-DeAngelis (BD) formula can describe the plant-pollinator interaction, the formula is extended in this paper to characterize the pollination mutualism under the ant interference. Then, a plant-pollinator-ant system with the extended BD functional response is discussed, and global dynamics of the model demonstrate the mechanisms by which pollination mutualism can persist in the presence of ants. When the ant interference is strong, it can result in extinction of pollinators. Moreover, if the ants depend on pollination mutualism for survival, the strong interference could drive pollinators into extinction, which consequently lead to extinction of the ants themselves. When the ant interference is weak, a cooperation between plant-ant and plant-pollinator mutualisms could occur, which promotes survival of both ants and pollinators, especially in the case that ants (respectively, pollinators) cannot survive in the absence of pollinators (respectively, ants). Even when the level of ant interference remains invariant, varying ants' negative effect on plants can result in survival/extinction of both ants and pollinators. Therefore, our results provide an explanation for the persistence of pollination mutualism when there exist ants.

Cyanobacteria are oxygenic photosynthetic prokaryotes that play important roles in the global carbon cycle. Recently, engineered cyanobacteria capable of producing various small molecules from CO2 have been developed. However, cyanobacteria are seldom considered as factories for producing proteins, mainly because of the lack of efficient strong promoters. Here, we report the discovery and verification of a super-strong promoter P(cpc560), which contains two predicted promoters and 14 predicted transcription factor binding sites (TFBSs). Using P(cpc560), functional proteins were produced at a level of up to 15% of total soluble protein in the cyanobacterium Synechocystis sp. 6803, a level comparable to that produced in Escherichia coli. We demonstrated that the presence of multiple TFBSs in P(cpc560) is crucial for its promoter strength. Genetically transformable cyanobacteria neither have endotoxins nor form inclusion bodies; therefore, P(cpc560) opens the possibility to use cyanobacteria as alternative hosts for producing heterogeneous proteins from CO2 and inorganic nutrients.

NMR surprizes with thin slices and strong gradients

Energy Technology Data Exchange (ETDEWEB)

Gaedke, Achim; Kresse, Benjamin [Institute of Condensed Matter Physics, Technische Universitaet Darmstadt (Germany); Nestle, Nikolaus

2008-07-01

In the context of our work on diffusion-relaxation-coupling in thin excited slices, we perform NMR experiments in static magnetic field gradients up to 200 T/m. For slice thicknesses in the range of 10{mu}m, the frequency bandwidth of the excited slices becomes sufficiently narrow that free induction decays (FIDs) become observable despite the presence of the strong static gradient. The observed FIDs were also simulated using standard methods from MRI physics. Possible effects of diffusion during the FID duration are still minor at this slice thickness in water but might become dominant for smaller slices or more diffusive media. Furthermore, the detailed excitation structure of the RF pulses was studied in profiling experiments over the edge of a plane liquid cell. Side lobe effects to the slices will be discussed along with approaches to control them. The spatial resolution achieved in the profiling experiments furthermore allows the identification of thermal expansion phenomena in the NMR magnet. Measures to reduce the temperature drift problems are presented.

Federalism and bioethics.

Science.gov (United States)

Von Hagel, Alisa

2014-01-01

The absence of comprehensive federal oversight of human biotechnologies in the United States continues to stimulate academic discourse on the relative merits of European-style regulatory agencies as compared to the current, decentralized approach. Many American bioethicists support the latter, maintaining that the key features of federalism--policy experimentation and moral pluralism--allows for the efficient regulation of these complex and contentious issues. This paper examines state-level regulation of oocyte donation to assess claims regarding the superiority of this decentralized regulatory approach. Further, this paper introduces an additional element to this examination of state law, which concerns the degree to which the health and safety of key participants is addressed at the state level. This inquiry assesses one facet of fertility medicine and biomedical research law, oocyte donation, an analysis that can be used to inform the broader discourse regarding the regulation of human biotechnologies and bioethical issues by the states.

A model of film boiling in the presence of electric fields

Energy Technology Data Exchange (ETDEWEB)

Carrica, P.M.; Masson, V.; Clausse, A. [Centro Atomico Bariloche and Instituto Balseiro, Barilochi (Argentina)

1995-09-01

Recently it was found that, when a strong electric field is applied around a heated wire, two distinct film boiling heat transfer regimes are observed. In this paper, a semi-empirical model is derived to analyze the pool boiling process in the presence of non uniform electric field. The model takes into account the dielectrophoretic force acting on the bubbles as they grow and the effect of the electric field on the most dangerous wavelength. It is shown how the transition between the two film boiling regimes is possible for high strength electric fields. The threshold voltage for transition, transition heat fluxes and hysteresis values are compared with experimental outcomes showing a satisfactory agreement.

Lactose behaviour in the presence of lactic acid and calcium.

Science.gov (United States)

Wijayasinghe, Rangani; Vasiljevic, Todor; Chandrapala, Jayani

2016-08-01

Physical properties of lactose appeared influenced by presence of lactic acid in the system. Some other components such as Ca may further attenuate lactose behaviour and impact its phase transition. A model-based study was thus implemented with varying concentrations of Ca (0·12, 0·072 or 0·035% w/w) and lactic acid (0·05, 0·2, 0·4 or 1% w/w) in establishing the effects of these two main acid whey constituents on lactose phase behaviour. Concentrated solutions (50% w/w) containing lactose, lactic acid and Ca were analysed for thermal behaviour and structural changes by Differential Scanning Colorimetry (DSC) and Fourier Transform Infrared Spectroscopy (FTIR), respectively. Presence of 1% (w/w) lactic acid and 0·12% (w/w) Ca in lactose solution significantly increased the evaporation enthalpy of water, delayed and increased the energy required for lactose crystallisation as compared to pure lactose. FTIR analysis indicated a strong hydration layer surrounding lactose molecules, restricting water mobility and/or inducing structural changes of lactose, hindering its crystallisation. The formation of calcium lactate, which restricts the diffusion of lactose molecules, is also partly responsible. It appears that Ca removal from acid whey may be a necessary step in improving the processability of acid whey.

An Analysis of the Social Media Presence of the Brands

Directory of Open Access Journals (Sweden)

OTILIA-ELENA PLATON

2014-05-01

Full Text Available Brands need to be close to consumers. The pursuing of this objective convinced an increasing number of companies to start using social media tools, such as social networks or blogs, in order to communicate with a great number of consumers. Hence, social media is rapidly turning into an important part of the brand communication strategy. The power of social media marketing can help the companies to create brand awareness and also to enhance the consumers’ engagement with a brand. Nowadays people seem to enjoy being part of an online brand community. Building a strong social media presence is an efficient way to generate high visibility for the brand. But the companies looking to reach greater exposure for their brand have to vie with dozens of other brands that seek to gain the same consumers’ attention. This is why the authenticity and the credibility are essential aspects that increase the chances of success. Based on the investigation of secondary data sources, this paper aims to analyze the social media presence of some of the most successful brands in Romania. Looking at some examples of social media marketing campaigns, this paper will outline the importance and the impact of such practices for the long-lasting customer relationship and the brand image.

Vacuum in the presence of electromagnetic fields and rotating boundaries

International Nuclear Information System (INIS)

Manogue, C.A.

1984-01-01

Two investigations of the properties of the vacuum are made. The first is a reconsideration of the classic Klein paradox, particle creation due to the presence of very strong external electromagnetic potentials. Expectation values of the current, momentum, and number operators, each of which is a measure of particle creation, are calculated for both massive spin zero and massive spin one half fields. The relationship between super-radiance and pair creation is explained. A review of past work by other authors is included and common conceptual errors are pointed out. The second investigation concerns the rotation of the vacuum caused by the rotation of boundaries. Just as the presence of boundaries can create a change in the vacuum expectation value of the energy density (the Casimir effect), the rotation of such boundaries can create changes in the vacuum expectation value of the momentum density. Calculations of the Casimir effect are made for a massless scalar field confined to an infinitely long square box. The change in the vacuum expectation value of the momentum density is calculated if this same box is rotating around its long central axis. In contrast, it is shown that for an infinitely long circular cylinder there is no change in the momentum density

Using virtual reality technology for aircraft visual inspection training: presence and comparison studies.

Vora, Jeenal; Nair, Santosh; Gramopadhye, Anand K; Duchowski, Andrew T; Melloy, Brian J; Kanki, Barbara

2002-11-01

The aircraft maintenance industry is a complex system consisting of several interrelated human and machine components. Recognizing this, the Federal Aviation Administration (FAA) has pursued human factors related research. In the maintenance arena the research has focused on the aircraft inspection process and the aircraft inspector. Training has been identified as the primary intervention strategy to improve the quality and reliability of aircraft inspection. If training is to be successful, it is critical that we provide aircraft inspectors with appropriate training tools and environment. In response to this need, the paper outlines the development of a virtual reality (VR) system for aircraft inspection training. VR has generated much excitement but little formal proof that it is useful. However, since VR interfaces are difficult and expensive to build, the computer graphics community needs to be able to predict which applications will benefit from VR. To address this important issue, this research measured the degree of immersion and presence felt by subjects in a virtual environment simulator. Specifically, it conducted two controlled studies using the VR system developed for visual inspection task of an aft-cargo bay at the VR Lab of Clemson University. Beyond assembling the visual inspection virtual environment, a significant goal of this project was to explore subjective presence as it affects task performance. The results of this study indicated that the system scored high on the issues related to the degree of presence felt by the subjects. As a next logical step, this study, then, compared VR to an existing PC-based aircraft inspection simulator. The results showed that the VR system was better and preferred over the PC-based training tool.

Intermittent strong transport of the quasi-adiabatic plasma state.

Science.gov (United States)

Kim, Chang-Bae; An, Chan-Yong; Min, Byunghoon

2018-06-05

The dynamics of the fluctuating electrostatic potential and the plasma density couched in the resistive-drift model at nearly adiabatic state are simulated. The linear modes are unstable if the phase difference between the potential and the density are positive. Exponential growth of the random small perturbations slows down due to the nonlinear E × B flows that work in two ways. They regulate the strength of the fluctuations by transferring the energy from the energy-producing scale to neighboring scales and reduce the cross phase at the same time. During quasi-steady relaxation sporadic appearance of very strong turbulent particle flux is observed that is characterized by the flat energy spectrum and the broad secondary peak in the mesoscale of the order of the gyro-radius. Such boost of the transport is found to be caused by presence of relatively large cross phase as the E × B flows are not effective in cancelling out the cross phase.

Natural Cold Baryogenesis from Strongly Interacting Electroweak Symmetry Breaking

CERN Document Server

Konstandin, Thomas

2011-01-01

The mechanism of "cold electroweak baryogenesis" has been so far unpopular because its proposal has relied on the ad-hoc assumption of a period of hybrid inflation at the electroweak scale with the Higgs acting as the waterfall field. We argue here that cold baryogenesis can be naturally realized without the need to introduce any slow-roll potential. Our point is that composite Higgs models where electroweak symmetry breaking arises via a strongly first-order phase transition provide a well-motivated framework for cold baryogenesis. In this case, reheating proceeds by bubble collisions and we argue that this can induce changes in Chern-Simons number, which in the presence of new sources of CP violation commonly lead to baryogenesis. We illustrate this mechanism using as a source of CP violation an effective dimension-six operator which is free from EDM constraints, another advantage of cold baryogenesis compared to the standard theory of electroweak baryogenesis. Our results are general as they do not rely on...
